Abstract: Molecularly imprinted polymers (MIPs) are a promising technology for sensing specific analytes. Structured MIP-coated quartz crystal microbalance sensors were developed for the detection of bisphenol A (BPA) using 2-dimethylaminoethyl methacrylate (DMAEMA) as a functional monomer. A simple unidirectional rubbing technique and a soft lithographic technique were used to fabricate convex hemispherical and hierarchical hemispherical MIP patterns, including a planar MIP film as a control. The two structured MIP films exhibited relatively higher imprinting factors and sensitivities compared with the planar MIP film and the selectivity coefficients of the structured MIP films were slightly increased due to the MIP structuring effect
