Microfluidics for Encapsulation: Pinball Style

IME researchers have developed a novel microfluidics technique which uses micropillars to generate and encapsulate polyelectrolyte microcapsules. With the proposed technique, the deposition of three bi-layers of polyelectrolytes was demonstrated in less than 3 minutes, significantly faster than conventional bulky methods that take up to several hours. The set-up is simple in design, scalable and uses a fraction of the chemical consumption required. The new technique is suitable for biomedical and food processing applications involving drug encapsulation and food emulsification, respectively.
