1. A method for selective deposition of molecules, comprising the steps of:
- (a) providing a reactive layer comprising a surface region coated with a resist that is biologically compatible with the reactive layer;
(b) selectively removing a portion of the biologically compatible resist from the surface region to expose an exposed portion of the reactive layer; and
(c) conjugating molecules with the exposed portion of the reactive layer;
wherein the reactive layer comprises chitosan.

Abstract
A method for biolithographical deposition of molecules is provided. According to an embodiment of the method, a reactive layer (e.g., a polysaccharide mass) having a surface region coated with a biologically compatible resist is provided. A portion of the biologically compatible resist is selectively removed to expose an exposed portion of the reactive layer. Molecules, such as biomolecules and/or cellular species, are then conjugated to the exposed portion of the reactive layer. Also provided are materials and devices related to the method.
