CCB Colloquium presentation by Dr. Muhammad N. Yousaf, University of North Carolina at Chapel Hill.

Host: Dr. KiBum Lee

Talk Title: "Integrating surfaces with organic chemistry applied to dynamic studies of cell behavior and the development of biomaterials for cell tissue engineering"

Abstract: This seminar will describe two recent projects. 1. Interfacing surface chemistry with cell biology to generate new proteomic microarrays and dynamic surfaces to study cell behavior and stem cell differentiation. 2. The development of new biodegradable biomaterials via a general synthetic chemoselective redox responsive ligation (click) and release strategy applied to cell surface engineering to control dynamic 3-D cell tissue interactions.
