Abstract
Drug-testing technologies, biosensor fabrication, tissue engineering, and basic biological research depend strongly on the patterning of live animal cells. Current techniques for controlling cellular adhesion are restricted with two primary limitations. Firstly, the complexity of the available patterns is very limited and, secondly, the pallet of materials that induce cellular patterning is exhaustible. Here, we demonstrate a method for computer-aided control of cell patterning using a scientific inkjet printer that yields a highly complex cellular pattern suitable for applications in regenerative medicine and rapid prototyping, and a strategy for using in situ polymerization for fabrication polymeric patterns directly on-chip.
