Active Manipulations and Control in Droplet-Based Microfluidics

Friday, August 10, 2018
SSB 7172 @ 1:30 p.m.

Host: Dr. Paul Li

Abstract

Droplet-based microfluidics is an interdisciplinary research field that intertwines various disciplines and branches of sciences. This field spans across areas that involves physics, chemistry, biology to engineering branches such as material, environmental, biomedical and computer science. One of the important aspect in droplet-based microfluidics is the ability to control and manipulate discrete droplets. This is because the individual droplets serve as microreactors for various chemical and biological processes. In this talk, I will first present my past works which demonstrates different approaches to manipulate and control droplets. These works includes the microfluidic jukebox, dancing droplets in microchannels and the use of negative pressure to generate droplet on demand. In the second half of the talk, I will present my works on the integration of Artificial Intelligence (AI) into droplet-based microfluidics. The use of AI allows automated and autonomous processing, analysis and handling of droplets at the microscale. This impeccable marriage between the two fields brings about an exciting paradigm shift in both technological capabilities and approaches. In the last part of the talk, I will present my on-going work on a new on-demand droplet splitting concept. This exciting new work allows droplets to navigate through pillars which may be used for various liquid encoding processes.
