Breaking new boundaries with microfluidics

Abstract

Microfluidics is an important emerging research platform in South Africa. It deals with the control and manipulation of very small quantities of fluids (typically microlitre and smaller) inside micro-channels. Microfluidic-based devices show great promise for easy-to-use, inexpensive, point-of-care health diagnostics. Microfluidic devices also serve as excellent tools for the facilitation of micro reactions in droplets. The CSIR has taken the lead in establishing research and development facilities for microfluidics in these fields. We report on the facilities which are available and give an overview of the projects which are being undertaken in this field. These projects include the generation of emulsions for advanced particle production, the research into components to be integrated into an HIV/Aids diagnostic device and the development of a hand-held diagnostic device to be utilised for environmental and human health applications and other health-related issues. In addition, work on the development of conducting polymers, aimed specifically at reducing the number of components in micro fuel cells, is described. Finally, we report on the establishment of a Microfluidics Research Network in South Africa, aimed at creating the space for researchers involved in microfluidics and related fields to interact with one another, including the sharing of information, organization of specialised conferences and collaborations between researchers.
