Abstract
Globally, there is growing concern about the health risks of water and air pollution. The U.S. Environmental Protection Agency (EPA) has developed a list of priority pollutants containing 129 different chemical compounds. All of these chemicals are of significant interest due to their serious health and safety issues. Permanent exposure to some concentrations of these chemicals can cause severe and irrecoverable health effects, which can be easily prevented by their early identification. Molecularly imprinted polymers (MIPs) offer great potential for selective adsorption of chemicals from water and air samples. These selective artificial bio(mimetic) receptors are promising candidates for modification of sensors, especially disposable sensors, due to their low-cost, long-term stability, ease of engineering, simplicity of production and their applicability for a wide range of targets. Herein, innovative strategies used to develop MIP-based sensors for EPA priority pollutants will be reviewed.
Highlights
This review aims to provide an overview of the developed strategies for modification of sensor devices, that work based on different detection techniques, with Molecularly imprinted polymers (MIPs) (MIP particles or MIP thin layers were used either directly or in a nanocomposite) for a broad range of important chemicals with different physical-chemical properties
We believe that the modification of these low-cost Screen-printed electrode (SPE) with imprinted polymer nanoparticles or thin layers, using new synthesis strategies, offers a great potential to develop new selective disposable sensors for Environmental Protection Agency (EPA) Priority Pollutants detection
MIP-modified sensors for EPA Priority Pollutants were reviewed from three different aspects including sensor devices/detection techniques, polymerization and modification methods
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. In for MIPs were obtained in early 1970s using covalent approach In this method, the comthis method, the complexation between template and functional monomers are based on plexation between template and functional monomers are based on covalent bonds that are covalent bonds that are cleaved and must bethe regenerated cleaved after polymerization and after must polymerization be regenerated again during recognitionagain produring the recognition.
