Patent ID: 8702792

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 into an environment in which said device is located; a second imprint molecule comprising an analyte present in said environment in which said device is located; a first electroactive molecularly imprinted polymer imprinted with said first imprint molecule, said first electroactive molecularly imprinted polymer also having a plurality of first binding sites capable of binding said first imprint molecule, each of said first binding sites characterized by a binding affinity between said first binding site and said first imprint molecule; and a second electroactive molecularly imprinted polymer imprinted with said second imprint molecule and having a plurality of second binding sites capable of binding said second imprint molecule, each of said second binding sites characterized by a certain binding affinity between said second binding site and said second imprint molecule; wherein binding of said second imprint molecule to said second electroactive molecularly imprinted polymer creates an electric potential between said second electroactive molecularly imprinted polymer and said first electroactive molecularly imprinted polymer; wherein said first electroactive molecularly imprinted polymer has a predetermined density of said first imprint molecules bound at said first binding sites; wherein when a sufficient potential is produced between said second electroactive molecularly imprinted polymer and said first electroactive molecularly imprinted polymer, electrons transfer from said second electroactive molecularly imprinted polymer to said first electroactive molecularly imprinted polymer causing said binding affinity between said first binding site and said first imprint molecule to decrease so that said first imprint molecule is released from said first binding site and thereby delivered by said device into said environment, and wherein said first electroactive molecularly imprinted polymer and said second electroactive molecularly imprinted polymer are conducting polymers.
