Electric Lithography: Sub-micrometer Protein Patterning

Electric Lithography: Sub-micrometer Protein Patterning - Y. Chang and co-workers of the University of California, Los Angeles, USA, report an electric lithographic (EL) technique to generate protein patterns with sub-micrometer resolution on a poly(N-tBOC-2-aminoethyl methacrylate) surface. In the EL process, an electric potential is applied between metal patterns on a mask and the poly(N-tBOC-2-aminoethyl methacrylate) layer to electrochemically induce the dissociation of the tBOC from the amine functional groups. more
