Paper has also been widely used to support the fabrication of composite paper/MIP membranes. These membranes were applied for solid-phase extraction experiments , drug delivery systems , as selective recognition elements in optical sensors . There is also one example of microfluidic thermal detection over MIP/paper chemosensor . Importantly, in all these sensors, the paper serves only as a solid support for the MIP synthesis in form of a membrane or it can be also applied as support for MIP film-based electrochemical sensors . However, to have appreciable sensitivity different nanomaterials were employed . For instance, a paper was decorated with Au and ZnO NPs . This material was conductive enough to electropolymerize pentachlorophenol-imprinted polypyrrole film on the top. Then, ascorbic acid was exploited as an efficient electron donor for scavenging photo-generated holes, facilitating the generation of stable photocurrent. This photocurrent decreased with increasing pentachlorophenol concentration. Moreover, paper modified with paraffin wax and carbon ink was applied as electrode material in the MIP film electrochemical sensor for bovine serum albumin (BSA) determination . BSA-MIP film was synthesized via free-radical polymerization, and after BSA template removal, the fabricated electrode was applied for impedimetric BSA determinations. However, selectivity performance nor imprinting factors were reported in both cases. Therefore, it is difficult to determine if imprinting process was successful.
