Les particules à patchs magnétiques ont pris une importance toute particulière dans l’étude des assemblages vers de nouvelles structures colloïdales. L’état de l’art nous a montré que la majorité des systèmes synthétisés et étudiés concerne des particules à un seul patch magnétique limitant ainsi les possibilités de structures accessibles par assemblage. Notre objectif s’est donc centré sur l’obtention de nanoparticules sphériques de polystyrène (PS) porteuses de plusieurs nanoparticules superparamagnétiques à leur périphérie. La voie multi-étapes retenue a consisté à préparer par polymérisation en émulsion ensemencée des particules Janus magnétiques (MJPs) présentant un nodule de PS qui a ensuite été rendu « collant » dans un mélange de bon/mauvais solvant pour fusionner avec celui d’un nombre limité de particules similaires. Pour servir de patchs magnétiques d’environ 100 nm, nous avons préparé des supraparticules colloïdales de nanoparticules d’oxyde de fer superparamagnétiques par un procédé incluant des étapes d’évaporation d’une phase émulsifiée, de consolidation par la silice et de resserrement de la distribution de taille par purification. Les paramètres optimaux de la polymérisation en émulsion ensemencée (composition du mélange de tensioactifs, nature et taux de greffage de l’agent de couplage) et de l’assemblage (nature et fraction du bon solvant, concentration particulaire, température et durée d’incubation) ont été préalablement déterminés avec des nanoparticules-modèles de silice présentant un diamètre et un état de surface similaires. L’application de ces conditions aux MJPs s’est avérée plus compliquée que prévue notamment en raison de la faible quantité de supraparticules disponible et cela a notamment conduit à définir de nouvelles conditions de polymérisation en émulsion ensemencée. Finalement, des lots de nanoparticules de latex à deux ou trois patchs magnétiques ont été obtenus, mais nécessiteront des étapes de purification avant d’envisager des études d’assemblage sous champ magnétique
Magnetic patchy particles are of great interest for assembly into novel colloidal structures. The state of the art showed us that the vast majority of synthesized and studied systems concerns particles with a single magnetic patch, thus limiting the structures accessible by particles assembly. Therefore, the main goal of the present study was to develop spherical polystyrene (PS) nanoparticles with two or many superparamagnetic nanoparticles on their surface. Our multistep process involved first the fabrication of Magnetic Janus particles (MJPs) by seeded-growth emulsion polymerization and subsequent incubation in suitable mixtures of good and bad solvents to make their polystyrene lobe “sticky”. MJPs are then ready to coalesce into self-assembled structures with small aggregation numbers. In order to obtain magnetic patches with a size range of 100 nm, we prepared colloidal supraparticles highly loaded with superparamagnetic iron oxide nanoparticles through a multistep procedure, including evaporation-induced emulsion, silica coating and purification, leading to a narrowing of the size distribution. The optimal parameters of the seeded-growth emulsion polymerization (surfactant mixture composition, coupling agent type, surface grafting density) and of the assembly (solvent quality, good solvent content, particle concentration, temperature and incubation time) were previously determined with silica nanoparticles as models with similar particle diameter as well as surface chemistry. We demonstrated that under the same conditions MJPs synthesis became trickier, mainly because of the small amount of available supraparticules. This led us to implement new seeded-growth emulsion polymerization conditions. Finally, batches of latex nanoparticles with two or three magnetic patches were obtained, but required further purification steps before investigating their assembly behavior under magnetic field

With great strides in neuroscience that have been made in the past decade, further understandings of complex neural systems require extensive neural information from chronic implantation of biocompatible neural devices. Polyimide-based flexible microelectrode arrays were one of the earlier biocompatible neural devices due to its mechanical impedance matching with brain tissue. In this work, we propose to incorporate non-conventional laser ablation method for fabrication of flexible biocompatible microelectrodes. We also present a novel approach to modifying flexible microelectrodes with macroporous platinum film using latex polystyrene sphere template. Maskless laser ablation was used to pattern the electrode, and probe definition as well creating the contact openings of flexible polyimide electrodes. Laser ablation is a non-photolithographic method which does not require conventional cleanroom environment and is ideal for rapid prototyping of devices. An ordered polystyrene bead template was deposited by simple pipetting of bead solution over gold contact openings and evaporating in ambient room setting. Pulsed-potentiostatic mode electrochemical deposition of platinum through the polystyrene bead template resulted in increase in effective surface area of electrodes. The impedance of the platinum modified electrodes increased by two orders of magnitude compared to unmodified electrodes. Synergetic modification of microelectrodes with macroporous platinum film and polymer-brush coating can lead to fabrication of highly biocompatible microelectrode with low impedance characteristics.

This paper presents a theoretical and experimental investigation on the irreversible deposition of colloidal particles from electrokinetic microfluidic flow in parallel plate channels. The electrokinetic particle transport model presented in this study is based on the stochastic Langevin equation, incorporating the electrical, hydrodynamic, DLVO colloidal interactions and random Brownian motion of colloidal particles. The particle trajectories are computed via the Brownian dynamics simulation technique and the particle deposition is quantified in terms of the surface coverage. Direct videomicroscopic observation using the parallel-plate flow cell technique, is employed to determine the deposition kinetics of polystyrene latex particles in NaCl electrolytes. The theoretical predictions are compared with experimental results, and a reasonable agreement is found.

Dielectrophoresis (DEP) has been successfully applied and demonstrated to provide novel and non-invasive means for characterizing, manipulating, trapping, separating and isolating microscopic sized particles, including biological cells. In this article, we report on the design, fabrication and performance of a novel, low cost, integrated Poly(dimethylsiloxane) (PDMS)/DEP microfluidic device capable of controlled manipulation of microscopic sized cells and particles that can be simultaneously utilized both for DEP spectral analysis and cell sorting. We have prototyped microfluidic channels, with DEP microelectrodes incorporated within PDMS channels. Previously, we have evaluated the operation and performance of a prototype device using various dielectric and biological particles, including yeast cells and polystyrene latex beads. In this paper, we report initial experimental observations on malignant cancerous cells. Non-viable cells, due to positive DEP, were attracted to the planar electrodes at frequencies between 200–600 kHz and were clearly repelled from the electrodes, due to negative DEP, at frequencies above 10 MHz.

We study numerically, using the Mie theory, light transmission through a multiply scattering medium composed of a collection of uncorrelated, optically inactive spherical particles. The characteristic length over which a plane wave field is depolarized depends on whether it is initially linearly or circularly polarized and of the size of the particles. In a medium containing particles small compared to the wavelength (Rayleigh regime), the characteristic length of depolarization for incident linearly polarized light is found to exceed that for incident circularly polarized light, while the opposite is true in a medium composed of particles large compared to the wavelength (Mie regime). Comparison of numerical results with data from measurements on suspensions of polystyrene latex spheres in water is made. Agreement between these simulations and experiment is good for the range of sizes considered in this paper. We also discuss the relevance of the helicity flip model to the analysis of these data.

Optical trapping technique, which uses a strongly focused laser beam1), has become an important tool for the precise manipulation of micrometer-sized particles such as polystyrene latex spheres2) and biological cells3). Almost the particles shown to be trapped are spheres, because the production of shape-controlled particles in micrometer range was quite difficult. Recently, mono-disperse hematite (α-Fe2O3) particles, of which both the shape and the size are simultaneously well-controlled, are produced by the gel-sol method4). It has been revealed that several types of the particle shape, for example, pseudo-cubic and peanut-type, are obtainable. It is very interesting to apply these shape- and size-controlled particles to optical trapping and investigate the feature of the trapped particles. With regard to the micro structure fabrication, these mono-disperse particles are also attractive to use as model parts. We believe that the micro structure fabrication achieved by using optical trapping will be the basis of nanostructure fabrication because nanometer-sized particles, for example, 26 nm silica1) and 36 nm gold particles5), have been demonstrated to be optically trapped.

Abstract Collection of airborne bacteria (bioaerosols) is of interest for a variety of public health and national security concerns. A novel microfabricated virtual impactor device is being developed to concentrate bioaerosol particles in the 1 to 3 micron size range, which is typical of a single bacterial spore. The concentration is from a large to a small volume of air, with target concentration factors between 5 and 50. A virtual impactor uses the particle’s inertia to separate it from the main flow stream. Our design represents a significant departure from existing virtual impactor technology: the particle laden flow is directed into planar rows of virtual impactor elements. This novel architecture is described in detail in this paper. The use of computational fluid dynamics has led to designs in which each impactor row is specialized. Polystyrene latex (PSL) spheres simulate the bioaerosol particulates in our experiments. The experimental results show trends that do not correlate with the simulations. The data support our hypothesis that surface roughness may result in turbulent mixing within the virtual impactor elements, thereby reducing the effectiveness of the concentrator. Additional study of the effect of surface roughness and turbulence within the virtual impactor is planned.

Recently, researchers have been attracted towards the gas production from hydrate bearing sediments considering its abundance in marine continental margins and persisting demand for alternate energy. Dissociation of hydrate into gas and water is the preliminary technique for gas production in hydrate bearing sediments. Expanded fluid volume and gas pressure upon dissociation detach the fines from the grain surface and result in pore throat entrapment. Migration of fines associated with gas flow greatly influence the alteration of permeability of the sediment by clogging pore throats in the flow path. A pore-scale visualization study was implemented to provide a clear insight into the actual mechanisms associated with mobilization and clogging of fines during two-phase flow through a microfluidic chip. Carboxylate modified polystyrene latex particles deposited in the porous media were migrated during drainage with CO2 gas. The detachment of fine particles from the grain surfaces was observed and were retained on the new interface; gas-water interface. The images and videos captured during the experiment were helpful in observing additional pore scale mechanisms responsible for permeability impairment in the porous media. Interface pinning, deformation and resistance to coalescence were found to be other mechanisms in addition to pore clogging.
