A novel method to prepare SPR sensor chips based on photografting molecularly imprinted polymer

A novel method to prepare surface plasmon resonance (SPR) sensor chips based on grafted imprinted polymer is explored. Benzophenone photografting system is used to grow molecularly imprinted polymer (MIP) films from the modified surface of gold substrate. The surface morphology and thickness of MIP films were investigated by scanning electronic microscope (SEM). The adsorption properties of sensor chip were studied by SPR spectroscopy. The results demonstrate that nano-MIP films can be constructed on the surface of gold substrate with the good adsorption of template molecules.
