Micro and Nano Fluidics:

Microfluidic Pumps and Stirrers

We are making use of what we have learned about micro fluidics to develop point-of-care devices for various medical applications. For example, in collaboration with the dental school and a company, we are studying and developing a portable system for rapid diagnosis of pathogens in oral fluids.
