Paper on the separation of bio-particle for CTC application just published in Sci. Rep.

In this paper, we investigate dielectrophoretic filtration, in which channel size and separation performance are decoupled. By simulating microfluidic model porous media, we derive design rules for DEP filters and verify them using model particles (polystyrene) and biological cells (S. cerevisiae, yeast). Our microfluidic approach provides new insight into trapping dynamics in porous media, which even can be applied in real sponges. These results pave the way toward high-throughput retention, which is capable of solving existing problems such as cell separation in liquid biopsy or precious metal recovery. Congrats to Georg, Shaurya and Samir!

Dayinta and Lea’s paper has been published in Scientific Reports!

In this paper, we have investigated the role of gel-phase lipids in the electroporation of binary giant unilamellar vesicles (GUVs), composed from DPPC (gel-phase) and DPhPC (fluid-phase) lipids (molar ratio 8:2 and 2:8). We have observed that the exposure to electric pulses leads to expel of fluid-phase lipids and concomitant decrease in GUV size, whereas the gel-phase domains become buckled. Based on experiments on pure fluid-phase and gel-phase GUVs, we have found that fluid-phase lipids can be expelled by electrical forces and the highly viscous gel-phase lipids cannot. These results provide an insight on the role of the different domains in the membrane of living cells during electroporation. Congrats to Dayinta and Lea for a very nice paper!

Pouyan Boukany gave an invited talk in APS meeting!

From a broad view, there have been major developments in single polymer dynamics in recent years, including work focused on entangled solutions and direct imaging of topologically complex polymers, all of which is of high interest to the field of soft matter. Slide are available on line. Congrats!

Paper on nanoparticle sintering in ALD of supported catalysts published! Congratulations Fabio!

This paper addresses two central aspects of industrial catalysis: the synthesis of catalysts based on supported nanoparticles and nanoparticle sintering. In particular, we employ a modelling approach to understand and describe the role of sintering in the synthesis of supported nanoparticles via a technique that in the coming years might bring atomic-level precision to the large-scale synthesis of catalysts: atomic layer deposition (ALD). The analysis in the paper provides the key of interpretation of the evolution of experimental observables such as the nanoparticle size distribution, the nanoparticle density, and the material loading.

Paper on the slip behaviour of DNA solution is published in Biomicrofluidics

In this paper, we investigate the slip behavior of an entangled DNA solution at a molecular scale using a confocal microscope coupled to a microfluidic device. By imaging DNA conformations during both channel and shear flows on different surfaces, we elucidate that either chain desorption or flow-induced stretching of adsorbed chains occurs depending on the surface condition. In general, we expect that these new insights into the slip phenomenon will be useful for studying the biological flow involving single DNA molecule experiments in micro/nanofluidic devices. Congratulations!

Work of lead authors Fabio Grillo and Hao Bui is featured in Phys. Chem. Lett. Spotlights

In this work, they studied the evolution of the PSDs of platinum nanoparticles in oxygen-based platinum atomic layer deposition on bulk quantities of graphene nanoplatelets. Our findings depart from the current atomistic understanding of the formation and growth of platinum nanoparticles in atomic layer deposition, where layer-by-layer growth and Ostwald ripening are thought to be the dominant mechanisms. Instead, the growth of the nanoparticles is best described in terms of Smoluchowski aggregation, i.e., nanoparticle diffusion and coalescence. Our report may inform the study of the diffusion, assembly, and stability of supported nanoparticles. Furthermore, their paper was selected for the Spotlights section of the journal. Congratulations, Fabio and Hao!

Congratulations to Hao, Fabio and Sharath for their paper on low temperature ALD delivering more active and stable Pt-based catalysts

Our work marks a significant advance in the synthesis of size-selected nanoparticles (NPs) on high-surface-area supports. We show that by extending the operating regime of atomic layer deposition (ALD) of platinum to low temperatures (i.e., 100 °C) one can deposit Pt nanoparticles that, compared to their high-temperature counterparts, boast not only narrow particle size distributions (PSD) but also high activity and stability towards propene oxidation. Our approach provides not only a viable route for the scalable synthesis of stable supported Pt NPs with tailored size distributions but also a tool for studying the structure-function relationship of Pt-based catalysts.

Serhii and Kartik's paper on all aqueous microfluidics has been published in RSC Advances

In this paper, Serhii and Kartik present a method for all-aqueous, continuous microfluidic production of core-shell hydrogel microcapsules. Using the device with a 3D architecture allowed them achieving spontaneous break-up of a water-in-water jet into two-phase core-shell droplets, followed by UV-polymerization of their shells. Produced hydrogel microcapsules with a liquid core displayed excellent stability towards drying and rehydration, as well as to various harsh environments (3 < pH < 13). Their future work aims at controlling the encapsulation and release of cargo by tuning the permeability of the capsules’ shells. Congratulations, Serhii and Kartik!

Dayinta and Lea’s paper has been published in Advances in Colloid and Interface Science

In this article , we focus on the effects of pulsed electric fields on lipid vesicles ranging from giant unilamellar vesicles (GUVs) to small unilamellar vesicles (SUVs), from both fundamental and applicative perspectives. First, we discuss in detail how research on cell-size GUVs as model cell systems has provided novel insight into the basic mechanisms of cell electroporation and associated phenomena. Afterwards, we discuss how electroporation and electrofusion have been used as versatile methods to manipulate vesicles of all sizes in different biomedical applications. Discussion proceeds by summarizing the open questions in the field of electroporation and possible future directions for vesicles in the biomedical field. Congrats to Dayinta and Lea!

Paper on unraveling the mechanism of “Neck" formation in extensional flow is published in Macromolecules

In this paper , Shaurya and Aswin study and describe the conformation of polymer molecules during thinning and necking of polymeric droplets in an extensional flow provided by using microfluidics. To unravel the molecular picture behind these phenomena, we integrate a T-shaped microfluidic device with advanced fluorescece microscopy to visualize stained DNA molecules at the stagnation point within the necking region. We find that the individual polymer molecules suddenly stretch from their coiled conformation at the onset of necking. Congrats to Shaurya and Aswin for a very nice paper!

A Delft Global Project (Getting HOT) has been awarded.

Aedes mosquitoes are transmitters of viruses that can cause tropical diseases that are often accompanied with high fevers that can turn lethal. When a patient has a fever, it is often difficult to quickly make the right diagnosis of the underlying disease. In this project Eduardo Mendes (ASM), Luigi Sasso (3me), and Pouyan Boukany (PPE) will develop a colour sensor chip to simultaneously detect three viral tropical diseases: Zika, dengue and chikungunya, in a fast and affordable way. The chip, once integrated into a piece of hardware connected to a portable (or satellite) phone - telemedicine - will allow humanitarian missions to access virtually any region on the globe. Congrats to Eduardo, Luigi and Pouyan!

Paper on atomic and molecular layer deposition published in Chemical Communications

Paper on elastic instabilities during polymeric fluid flow in porous media published in Soft Matter

In this paper , Durgesh and Esteban describe how elastic instabilities occur during flow of polymeric fluids in porous media. We find that polymer solution flowing through a model porous media (Wi > 1) shows two distinct elastic instabilities. In the shear-thinning regime, we observe stationary dead zones upstream of the pillars. At higher shear rates (Wi), these dead zones are periodically washed away. Congrats to Durgesh and Esteban for a very nice paper, and thanks to our collaborators and co-authors Pacelli Zitha and Bill Rossen in CITG!

Paper on precursor utilization in ALD just published in Chemical Engineering Journal

Atomic layer deposition (ALD) carried out in a fluidized bed is an attractive method for making nanostructured particles, e.g. for catalysis or batteries. For scale-up it is a prerequisite that the ALD precursors are efficiently used, as they represent a major operating cost. Our paper aims at understanding and optimizing the precursor utilization efficiency using a multiscale modelling approach. We show that fluidized-bed ALD on high-surface-area powders is a forgiving process that can be carried out with virtually no precursor waste.

Phys. Rev. Lett. on Local and Global Hysteresis now published.

We proudly announce that our most recent work on pinning of droplets has just been published in Physical Review Letters. The paper by Michiel Musterd, Volkert van Steijn, Chris Kleijn and Michiel Kreutzer is entitled "Droplets on inclined plates: Local and global hysteresis of pinned capillary surfaces" and deals with a theory that accounts for constrained contact line motion. Including this constrained motion in the model allows a description of previously unexplained phenomenon for droplets on inclined plates. The theory paves the road to a fully predictive model of droplet pinning by identifying the effect of the droplet width as the sole contributor to the history effects at roll-off.

Volkert van Steijn granted tenure.

PPE’s research featured as cover story of Small and Advanced Healthcare Materials journals in one week (May/2014)

A team in chemical engineering (PPE, ASM and OM) has developed a new method to generate large arrays of micellar nanowires. On the front cover of Small journal our recent work has been highlighted with an image illustrating a novel, simple, and affordable method for generating a large array of laterally ordered soft nanowires from worm-like micelles. These micellar nanowires can be successfully decorated with hydrophobic molecules that incorporate into the micelle core or with hydrophilic nanoparticles such as quantum dots entrapped in the corona. This platform should enable new opportunities in functional nanoscale devices, especially bio-chemical sensors.


In the second publication, scientists from Delft, Ohio State and Duke University have found a safe and efficient way to deliver nanoparticles containing a wide range of biomolecules into living cells without going through the endocytosis route, by applying electrical pulses through a nanochannel. Pouyan E. Boukany, L. James Lee, Kam W. Leong and colleagues present a novel platform for in vitro nucleic acid delivery in regulating gene expression that holds great potential in advancing fundamental biological science and modifying cells for biomedical applications. This work has been recently published as the inside front cover story in Advanced Healthcare Materials, which is an international, interdisciplinary forum for peer-reviewed papers on materials science aimed at promoting human health.

Need Amphiphilic Nanowires? Check out our recent work in Small by Piotr Glazer and Leo Bergen!

Worm-like micellar fluids may be used in fracturing fluids in oil fields, but they could also one day help us to create core/shell nanowires for bio/chemical sensing applications, thanks to a new and simple de-wetting approach developed at TU-Delft. A team in chemical engineering has developed a new method to generate large arrays of micellar nanowires, which are capable of trapping both hydrophilic and hydrophobic molecules. We wrote this paper as a result of Leo’s Bachelor Project by collaboration among PPE, ASM & OM. The paper is available on the Small website. Congrats!

Adv. Healthcare Mater. paper on Nonendocytic Delivery of Nanoparticles into living cells now published!

Scientists from Delft, Ohio State and Duke University have now found a safe and efficient way to deliver nanoparticles containing a wide range of biomolecules into living cells without going through the endocytosis route, by applying electrical pulses through a nanochannel. The approach effectively facilitates the cellular uptake and release of siRNAs, DNAs and large plasmids from nanoparticles. This new concept provides a convenient, safe, and efficient approach for nucleic acid delivery in regulating gene expression. The paper is available on the Adv. Healthcare Mater. website. This work is also highlighted in MaterialsViews as Non-viral nanoparticle vectors delivering biomolecules more efficiently.

ERC Starting Grant for Pouyan Boukany

Pouyan Boukany

Pouyan Boukany is one of the European researchers to have been awarded a European Research Council (ERC) Starting Grant for his research ‘Engineering DNA Transfer into Cells by Precision in Electroporation’. The ERC Starting Grants aim to support young researchers who are about to consolidate their own research team and to start conducting independent research in Europe. The grant is about 1.5 million Euros for a five-year project. The overall aim of this ERC project is to achieve more efficient and safer non-viral gene delivery by elucidating the mechanism of the membrane electroporation and DNA transport at the molecular and subcellular level. In contrast to viral delivery methods, seeking to deliver nakedDNA to cells is considered the best safe alternative for medical applications. Electroporation promises to do just that, but currently it is a crude and inefficient technique at best. Pouyan will tackle this by performing experiments at single cell level and employing single molecule techniques to observe all electroporation process in real time.

Phys. Rev. Lett. paper on bubble-particle interaction now published!

In this paper, Hooshyar et al. experimentally investigate the effect of particles on the dynamics of a gas bubble rising in a liquid-solid suspension while the particles are equally sized and neutrally buoyant. They show that when a bubble rises through a suspension characterized by a low Stokes number (small particles), it will hardly collide with the particles and will experience the suspension as a pseudo-clear liquid. On the other hand, when the Stokes number is high (large particles), the high particle inertia leads to direct collisions with the bubble.

Paper with Weitz lab and Garstecki lab just accepted

In this paper, the authors introduce a new type of droplet generator in which the volume of droplets depends primarily on the geometry of the droplet generator, and not on flow rates nor on fluid properties. The advantage of the fixed-volume droplet generator is that it ensures generation of droplets of a single size, even in environments in which fluids cannot be delivered at constant rates, or in which the rates are difficult to tune to the requisite values. This is of particular importance to for example point-of-care diagnostic applications.

Water-in-water-in-water drops

All water drops in drops

Our paper on ATPS core-shell emulsions is published in Soft Matter. The paper, by lead author Iwona Ziemecka, is the result of a collaboration of the PPE group and the Self-assembling Systems group (PI: Jan van Esch). The work describes how double emulsions (droplets inside droplets) can be made using solutions of polymers in water. The work describes the first time that such a complex architecture could be made without the use of an oil phase. Not having an oil proved to be challenging: Iwona cleverly integrated piezo-electric elements on chip that facilitated the droplet-in-droplet formation. Applications will be related to the fact that the outside fluid, the drop and the inner drop are fully biocompatible.
The paper can be found at the Soft Matter website. Be sure to also check out the movies in the supplementary information!

ERC Starting Grant for Ruud van Ommen

Ruud van Ommen

Dr Ruud van Ommen has been awarded an ERC Starting Grant from the European Research Council. An ERC Starting Grant is awarded for a period of five years to scientists who lead an independent team or programme and have the potential to become world class researchers. The Grant is about 1.5 million euros. Dr Ruud van Ommen is involved in the use of ultra-thin coatings on nanoparticles. Coated nanoparticles offer future benefits in such fields as catalysis and energy storage and for medical uses. At a fundamental level however, very little is known about how these nanoparticles can be produced under controlled conditions and on a larger scale. Van Ommen aims to change that. The nanoparticles are coated by means of atomic layer deposition (ALD): gas-phase technology from the semiconductor industry used to deposit countless different materials.
