Patent ID: 8216300

Claim:
A device for delivery of a chemical or biological agent comprising: a first imprint molecule comprising said chemical or biological agent to be delivered by said device; a first electroactive molecularly imprinted polymer imprinted with said first imprint molecule, said first electroactive molecularly imprinted polymer also having a plurality of binding sites capable of binding said first imprint molecule, said binding sites characterized by a binding affinity between said binding site and said first imprint molecule; and an electric potential producing member, said electric potential producing member capable of creating an electric potential between said electric potential producing member and said first electroactive molecularly imprinted polymer; wherein said first electroactive molecularly imprinted polymer has a predetermined density of said first imprint molecule bound at said binding sites; wherein when a sufficient potential is produced between said electric potential producing member and said first electroactive molecularly imprinted polymer, said binding affinity between said binding site and said first imprint molecule is decreased so that said first imprint molecule is released from said binding site and thereby delivered by said device; and wherein said first electroactive molecularly imprinted polymer is of the class termed polyazine.
