Patent ID: 8252045

Claim:
A method of delivering a chemical or biological agent comprising: providing a device for delivery of a chemical or biological agent comprising: an electroactive imprinted polymer having a plurality of binding sites, each binding site being capable of existing in either a first electroconformation or a second electroconformation wherein said first electroconformation and said second electroconformation provide different physical conformations of said binding site; a chemical or biological agent bound within at least one binding site in said plurality of binding sites; and a means for creating an electric potential between said means for creating an electric potential and said electroactive imprinted polymer, said means being electrically connected to said electroactive imprinted polymer; activating said means for creating an electric potential so as to generate said electric potential in said electroactive imprinted polymer; said electric potential converting said at least one of said binding sites from said first electroconformation to said second electroconformation; and releasing said chemical or biological agent from said binding site to which it is bound as a result of said converting altering the physical conformation of said binding site wherein said electroactive imprinted polymer is of the class termed polyazine.
