Microfluidic Synthesis of Designed Colloidal Particles Using Structured Elastomeric Membranes

چکیده
We report a method for synthesizing various shaped colloidal microparticles using microfluidic devices with structured elastomeric membranes. These elastomeric membranes incorporated between two-layered channels have negative relief structures, and pneumatically actuated membrane leads to confinement of fluid inside structures. Using this microfluidic system, we demonstrate synthesis of various shaped microparticles with internal periodic structures by trapping photocurable silica suspension inside structures on the membrane and curing under UV light. The shape and iridescent color of microparticles could be controlled by design of structures on the membrane and size of silica particles, respectively.

High-speed fabrication of patterned colloidal photonic structures in centrifugal microfluidic chips.
In this paper, we report a rapid and facile method for fabricating colloidal photonic crystals inside microchannels of radially symmetric microfluidic chips which were made using soft-lithography. As the suspension of monodisperse silica or polystyrene latex spheres was driven to flow through the channels under the action of centrifugal force, the colloidal spheres were quickly assembled into f...
متن کاملNovel Migration Phenomena in Structured Microfluidic Devices
Microfluidic and lab-on-a-chip devices have gained widespread attendance in separation sciences since they are characterized by advantageous properties like a gain in throughput, time, cost, performance and analyte amount. Beyond these advantages, microfluidic devices open access to completely new separation or particle sorting phenomena far from thermal equilibrium based on Brownian motion and...

We have developed the first fully integrated microfluidic system for DNA sequencing-by-synthesis. Using this chip and fluorescence detection, we have reliably sequenced up to 4 consecutive bps. The described sequencer can be integrated with other microfluidic components on the same chip to produce true lab-on-a-chip technology. The surface chemistry that was designed to anchor the DNA to elasto...
متن کاملSynthesis of Calcium Fluoride Ultrafine Particles for the Preparation of Integral Asymmetric Cellulose Acetate/Calcium Fluoride Membranes
The present work reports on the synthesis of cellulose acetate (CA) asymmetric membranes with the incorporation of inorganic fluorides, CaF2 particles. These fillers of polymeric composites can, according to the literature, promote the ordering of the polymer matrix, which can lead to interesting permeation properties. In order to achieve that, fluorite (CaF2 ) fine particles were prepared by a...

This paper reports a novel method for in-situ formation of hydrogel membranes and geometrically controlled selfassembly of colloidal crystals in microchannels using one step stamping. The simple elastomeric stamp was made of PDMS from SU-8 patterned master using standard soft lithography. Then the selective hydrophobic pattern on the PDMS stamp surface was achieved using Pluronic F127 coating a...
