Self-Assembly Molecularly Imprinted Nanofiber for 4-HA Recognition

In this paper, we provided a self-assembly strategy to prepare surface molecularly imprinted polyaniline (PANI) nanofiber. The route provides simplicity, convenience, low cost, and high-productivity due to the omission of the template guided materials and their post-treatment. The molecularly imprinted PANI nanofibers could selectively bind the template (4-hydroxybenzoic acid) molecules, and the nanofibers have large adsorption capacity and fast uptake kinetics for target species. The PANI nanofibers could provide a good material for imprinting various organic or biological molecules toward applications in chemical/biological sensors and bioassay.
