| Shaurya Prakash, Rutgers Mechanical & Aerospace Engineering 12:10 PM, CCR 201 Microfluidic devices have been gaining interest for microchip separation systems. These devices and systems are often constructed using standard microfabrication methods in common materials such as silicon, glass, or polymeric substrates. These materials present several challenges including variable zeta potentials, analyte-wall interactions due to non-specific adsorption, and leakage current. In this presentation, I will discuss fabrication and surface modification within microfluidic devices by application of pre-formed polymeric coatings. Results for influence of these adherent surface layers on zeta potential and adsorption of bio-molecules will be presented. I will also discuss the stability of the modified surface to several microfabrication conditions likely used in the fabrication of these devices. Finally, a discussion of developing next generation devices with surface-mediated flow along with some recent results for manupulating flow characteristics in microfluidic devices will be presented.
