Stimulus-responsive hydrogels are important materials of the field of smart sensors, characterized by change in volume, morphology, or color in response to external stimuli such as light, temperature, pH, and magnetism. Poly(N-isopropylacrylamide) (PNIPAm) hydrogels as well-known thermo-responsive material show a shrinking of volume phase above lower critical solution temperature (LCST). Especially, gradient of the hydrogel freestanding film via nanostructuring allows bending motion due to difference of volumetric shrinkage in the hydrogel above LCST. This behavior can shows the different of bending motion by molecular recognition in molecularly imprinted polymer (MIP) film. Therefore, in this study, thermo-responsive bovine serum albumin (BSA)-imprinted hydrogel films with an one-side structured inverse opal are fabricated by UV-polymerization and their recognition properties of BSA are evaluated by bending behaviors of the freestanding film. |
