Abstract
Microparticles are found in a broad range of settings ranging from consumer products to drug delivery to diagnostics. Advanced applications drive the demand for more complex particles with enhanced functionality. This talk will discuss the efforts of the speaker and his research group in developing encoded microparticles using Stop Flow Lithography (SFL). Their SFL synthesis process couples the precise control of flow afforded by microfluidics and the sculpting of light by UV lithographic patterning. The speaker will first describe the fundamental principles in SFL and give demonstrative examples of particles that can be synthesized, ranging from soft blood cell mimics to ceramic gears. Next, he will discuss two methods to encode information into the particles, one for use in bioassays and the other for use in anticounterfeiting.
About the speaker
Prof Patrick Doyle received his PhD from Stanford University in 1997. He was postdoctoral fellow at Institut Curie from 1998 to 1999. He is currently Singapore Research Professor of Chemical Engineering at Massachusetts Institute of Technology.
Prof Doyle’s researches focus on the fundamental and applied topics in soft matter. Much of his research is in the realms of micro/nanofluidic technologies, DNA biophysics, and rheology. A burgeoning interest is the use of microfludics to synthesize microparticles for both fundamental colloidal studies and applications, such as multiplexed sensing, drug delivery and catalysis. His research group utilizes both experimental and computational approaches in their research in order to understand fundamental issues in a wide variety of applications ranging from lab-on-chip separations to polymer rheology.
Prof Doyle received awards including the CAREER Award from the US National Science Foundation, the Rothschild-Yvette Mayent-Institute Curie Award, 3M Innovation Fund Award, Pioneers of Miniaturisation Prize from Lap on a Chip, Royal Society of Chemistry and Corning Incorporated, etc.
