Microprinting of On-Chip Cultures: Patterning of Yeast Cell Microarrays Using Concanavalin-A Adhesion

Microprinting has been demonstrated effective in the patterning of surface regions for trapping cells used within microfluidic devices. In this study a polydimethylsiloxane (PDMS) silicone elastomer stamp was microfabricated and used to microstamp concanavalin-A (con-A; protein that binds to yeast) on a glass surface. Yeast cells, Saccharomyces cerevisiae, were brought into contact with patterned con-A producing an array of yeast microscale culture in an ordered array identical to the printed pattern.
