Description

Current fabrication methods of electronic or electroactive materials are inherently 2-D and involve expensive lithographic masks, complicated stamping, etc. Furthermore, current strategies have not proven useful for creating complex 3-D assemblies.

The use of direct-write lithography technique offers exceptional promise as a more direct assembly protocol for fabrication of functional bioelectronic elements. Soluble proteins are photo-crosslinked using multi-photon excitation (MPI). These photo-crosslinked structures are written using a mechanical xy stage to translate the laser beam across the coverslip. These structures can be created in various shapes including lines, boxes, and freestanding arcs.
