Publication number: 20100068820Abstract: An adhesive is provided containing at least one synthetic polymer with receptor sites that enable the selective capture or release of a target molecule. A polymer is synthesized by polymerizing and cross-linking a functional monomer or functional copolymers in the presence of a target or template molecule allowing for reversible interactions between the polymer and the target molecule. The target molecule may be extracted from the polymer creating receptor sites complimentary to the target molecule. Alternatively, the target molecule may remain in the polymer network and be controllably released. The molecularly imprinted polymer is formulated into an adhesive. The adhesive can be used as a component in an in-vitro diagnostic device to release template molecules or to capture target molecules in vacated receptor sites in the synthetic polymer.Type: ApplicationFiled: June 22, 2006Publication date: March 18, 2010Applicant: ADHESIVES RESEARCH, INC.Inventors: William Meathrel, Benjamin Wagner
