Carbon nanohorns (CNHs) and its functional products are employed as nanomaterial assemblies to fabricate new electrochemical sensor utilizing the electrospinning and self-assembly technique. This work will illuminate the relationship between detail nanoconstructure of carbon material and its electrocatalytic behavior. On the basis of the above results, electospun nanofibers which own the biomimetic recognition for hydroxide or amino group containing foodborne contaminants are prepared by coupling CNHs and specific molecular imprinted polymers (MIPs). Due to the sacrifical spacer strategy for fabricating process and the nanometer size of this material, this electrospun MIPs nanofibers exhibt improved molecular recognition capabilities. Thus, the MIPs nanofibers obtained above, playing a role of biomimetic recognition elements, are assembled on the sensing platform. Adopting the electrochemistry and electrochemiluminescence as the final detect method, the present electrospinning-imprinting nanofibers based sensor shows promising application for foodborne contaminants with simple operation and high efficiency. The main influences including various electospun polymers, controls parameter during electrospinning, the fabrication process of electropun MIPs etc. are investigated.This research will greatly expand the relative applications of CNHs, and open new application opportunities for the fabrication of new biomimetic sensors based on CNHs doped electrospun MIPs nanofibers.
