摘要

The presence of chemical pollutants in air, water, soil and food samples pose significant challenges due to their potential health risks and regulatory concerns. Therefore, detection and quantification of chemical pollutants in environmental samples is a necessary task. To combat this issue, molecularly imprinted polymer nanoparticles (MIP NPs) and imprinted nanocomposites (Imp NCs) emerged as promising sensing material. Their tunable surface properties, stability, and reusability make them superior alternatives to conventional sensors. Additionally, their ability to function in complex environmental matrices enhances their practical applicability. The development of MIP NPs and Imp NCs based sensors opened new horizon in field of pollutant monitoring technologies. The purpose of this review is to highlight recent advances in the MIP NPs and Imp NCs based optical sensors for detection of chemical contaminants. The review begins with discussion on various methods for preparing MIP NPs and Imp NCs based sensors with the advantages and disadvantages associated with each synthetic approach. Then detailed analyses on factors that influence the imprinting efficiency, such as selection of functional monomer, cross linker, porogen solvent and nanomaterials to optimize sensor performance. Furthermore, working of MIP NPs and Imp NCs based optical sensors discussed thoroughly. Special emphasis is given to optical detection techniques, including fluorescence, surface plasmon resonance (SPR), and Surface-enhanced Raman scattering (SERS). Then review provides comprehensive discussion on the practical application of MIP NPs and Imp NCs for screening chemical pollutants (pesticides, pharmaceutical drugs, dyes, explosives, polymeric compounds and other chemical pollutants). Thus, this review provide single source where all the information including synthesis, working mechanism and sensing application of MIP NPs and Imp NCs are available for researchers working in the field of imprinted sensing systems. This review is a sincere attempt to highlight the use of MIP NPs and Imp NCs based sensors, which will guide readers in designing futuristic sensing materials, and their integration with smart sensing platforms, such as portable and real-time monitoring devices, will help in developing next-generation pollutant monitoring technologies.
