Abstract: The invention pertains to an electrically conductive copolymer of the general formula I:
wherein
A is a first polymerizable monomer which produces an electrically conductive polymer when polymerized, and represents a polymerized unit of said monomer A in the electrically conductive polymer;
B is a second polymerizable monomer which when copolymerized with monomer A produces an electrically conductive polymer, and represents a polymerized unit of said monomer B in the electrically conductive polymer;
w is an integer greater than or equal to 0;
x is an integer greater than or equal to 1;
y is an integer greater than or equal to 0;
z is an integer greater than or equal to I;
11, and 12 are each independently covalent linkers or spacer arms;
13 is substituent group having a desired chemical functionality; and
Bt′ is selected from the group consisting of biotin and complexes of biotin with a molecule selected from the group consisting of avidin, streptavidin, derivatives of avidin
