Molecularly imprinted polymers (MIPs) have been extensively studied as a sensor since it provides improved reliability, cost effectiveness and rapid preparation. Polymer brushes have recently attracted considerable attention due to their unusual surface morphologies and properties. In our group, the preparation and characterization of novel sensors for bisphenol A (BPA) based on the MIP brush is reported. Moreover, the performance of different sensors made by controlling the brush thickness was compared. The MIP brushes were fabricated via atom transfer radical polymerization and made of 4-vinylpyridine, acrylamide, ethylene glycol dimethacrylate and bisphenol A as functional monomers, a crosslinking monomer and template molecule, respectively. The morphology of the polymer brushes were characterized by field emission scanning electron microscopy. Furthermore, the recognition properties toward BPA were analyzed using quartz crystal microbalance. |
