报告摘要:
Precise and effective manipulation (e.g., focusing, enrichment and sorting) of particles and cells is critical in many chemical, biomedical and environmental applications. This can be achieved in microfluidic devices by an externally imposed force field, which ranges from the ubiquitous gravity to electric, acoustic, optic and magnetic forces etc. Among this type of active approaches, electric particle (both biological and synthetic) control relies on electrokinetic phenomena and dielectrophoresis where the former pumps the particle solution via fluid electroosmosis and/or particle electrophoresis while the latter directs particles along or against electric field gradients; magnetic particle control is based on magnetophoresis which is able to deflect particles either along or against magnetic field gradients. Microfluidic particle manipulation can also be implemented by the use of an internally induced force field such as lift force. In this talk I will present the fundamental and applied studies completed and on-going in my group on electric field, magnetic field, and lift force-based particle and cell manipulations in microfluidic devices. Specifically I will talk about our results on particle and cell handling using reservoir-based dielectrophoresis (rDEP) and curvature-induced dielectrophoresis (C-iDEP) as well as diamagnetic particle manipulation in ferrofluids. Moreover, I will present our recently published results on continuous particle separation via the inertial lift force in hydrodynamic flows, and the elastio-inertial lift force in viscoelastic flows.
