Abstract: The stimuli-responsive hydrogels that show swelling-deswelling behavior by changing external conditions such as temperature and pH are promising as smart materials for sensors and DDS etc. In this study, bisphenol A (BisA)-responsive hydrogels were prepared by molecular imprinting using cyclodextrin (CD) as a ligand. The swelling ratios of BisA-imprinted hydrogel, nonimprinted hydrogel and polyacrylamide (PAAm) hydrogel were measured in a saturated aqueous bisphenol A solution. In the presence of BisA, BisA-imprinted hydrogel was shrunken, but nonimprinted hydrogel and PAAm hydrogel was not. The shrinking of BisA-imprinted hydrogel is due to the formation of the CD-BisA-CD cross-linking structures. These imply that the network of BisA-imprinted hydrogel memorized BisA. Furthermore, the BisA-responsive behavior of the hydrogels were investigated by measuring amount of bisphenol A adsorbed into the hydrogels.
