SUMMARY:Magnetic Liquids for Lab-on-a-Chip Applications, Leidong Mao -- 
DESCRIPTION:NanoSEC Seminar. Professor Leidong Mao of the University of Georgia Faculty of Engineering will be presenting his talk entitled "Magnetic Liquids for Lab-on-a-Chip Applications."Magnetic liquids (stable colloidal suspensions of magnetic nanoparticles), also called ferrofluids,
offer attractive alternatives to moving mechanical components in industrial machinery. When
made biocompatible, they are also used in dilute forms as contrast agents for magnetic
resonance imaging, or in drug delivery platforms. Recently, we have proposed and begun
implementing a series of micro-scale pumping, separation, mixing, particle/cellular manipulation,
and droplet generation platforms, all based on magnetic liquids. Our approach involves creating
localized magnetic fields within microfluidic devices to manipulate ferrofluids. The ultimate goal
is to create assays that are portable, cheap, disposable, rapid and completely label free.
Magnetic liquid offers a practical solution to overcome the diffusion barrier in micro- and nanoscale
biosensor assays. In this talk, we present some of the exciting results that depict our
progress to date.
