Application of molecularly imprinted polymers in electrochemical biosensors based on carbon nanomaterials

Over the recent years, Molecularly imprinted Polymers (MIPs) have attracted the attention of many scientists because of their outstanding ability to be used as natural receptors, high stability, low cost, and easy preparation in electrochemical biocomponents. These polymers are built by creating three-dimensional hollow spaces in which monomers and crosslinkers bind together in the presence of the target molecule as the desired analyte, and the target molecule, through its specific functional groups, forms a monomer- The crosslinker is attached, and this feature increases these polymers selectivity significantly. In addition to polymers, various nanomaterials such as graphene and carbon nanotubes are also used in electrochemical biosensors. In this paper, in addition to various techniques for making the electrode using molecularly imprinted polymers and carbon nanomaterials, and their mechanism of action, various aspects of the use of these polymers in electrochemical biosensors have been investigated. By understanding how these polymers work in the electrochemical biosensors, we can say that in the future we will see further advances in this technology.
