Artificial receptors for electrochemical sensing of bacteria

The present review summarizes the molecular imprinting approach to bacteria electrochemical sensing developed over the last five years. Designing artificial molecularly imprinted polymer (MIP) and aptamer receptors for bacteria sensing is more challenging than for analytes of small and even large molecules like proteins. This herein-considered challenge arises from the bacteria's large size and numerous functional groups in bacteria cell walls for which selective complementary recognizing sites imprinted in a polymer are puzzling to generate. Moreover, the morphological characterization and recognition mechanism of the MIPs is discussed here in detail.
