Abstract:
A method of synthesizing a plurality of different polymers on a surface of a substrate, comprising:(a) providing a substrate having a surface bearing multiple copies of a protective group removable on exposure to an electric field or electric current;(b) applying the electric field or electric current to the substrate to remove a protective group from a first known location on the surface of the substrate;c) exposing the surface of the substrate to a first protected monomer bearing a protective group removable on exposure to an electric field or electric current, whereby the protected monomer attaches to the first known location;(d) applying the electric field or electric current to the substrate to remove a protective group from a second known location on the surface of the substrate;(e) exposing the surface of the substrate to a second protective monomer bearing a protective group removable on exposure to an electric field or electric current, whereby the second protected monomer attached to the second known location;(f) repeating (b)-(e) while controlling the known locations on the surface of the substrate to synthesize a plurality of different polymers at known locations on the surface of a substrate.
