✦ Synopsis

Abstract

A microfluidic system was designed, fabricated and implemented to study the behavior of polyelectrolyte capsules flowing in microscale channels. The device contains microchannels that lead into constrictions intended to capture polyelectrolyte microcapsules which were fabricated with the well‐known layer‐by‐layer (LbL) assembly technique. The behavior of hollow capsules at the constrictions was visualized and the properties of the capsules were investigated before and after introduction into the device.

Time series of video frames showing capsules being compressed into a constriction.

We developed a novel <50-microm thick nano-porous bi-layer latex coating for preserving Gluconobacter oxydans, a strict aerobe, as a whole cell biocatalyst. G. oxydans was entrapped in an acrylate/vinyl acetate co-polymer matrix (T (g) approximately 10 degrees C) and cast into 12.7-mm diameter patch

Quality assurance in design: Quality Assurance has been defined by the B.S.I. as ‘all those planned and systematic actions necessary to provide adequate confidence that a structure, system or component will perform satisfactorily in service’. This important topic will be of particular interest to those engaged in the chemical, process, petroleum, nuclear, power production and civil engineering industries. Quality Assurance in Design take the form of a collection of papers given by leading experts at the Joint IMechE/IChemE Symposium.
