Professor Hansford’s research investigates the bio-material interface through the use of advanced micro/nanofabrication techniques. Our fabrication techniques have been demonstrated on a wide variety of biomaterials and advanced functional materials, and can be used for planar, curved, and multi-level microstructures for enhancing and controlling the attachment of cells and tissues. We use these engineered biomaterial surfaces to study cellular behaviors from cancer cell migration behaviors through enhanced implant-tissue attachment. We also develop advanced microdevices for studying cells and manipulating bio-fluids at the micro/nanoscale for cell and biomolecular manipulation as well as modulation of the cellular microenvironment.

Involves the development of generalized microfabrication protocols for polymers as well as advanced applications of polymer, glass, and silicon microdevices for biomedical applications.  The Hansford lab has expertise in microfabrication of a wide array of biomaterials (especially functional polymers), modification of materials surfaces for enhanced biocompatibility, and design of bioMEMS devices for cellular interactions.
