Abstract
Molecular Imprinting Polymer (MIP) technology is a technique to design artificial receptors with a predetermined selectivity and specificity for a given analyte, which can be used as ideal materials in various application fields. In the last decades, MIP technology has gained much attention from the scientific world as summarized in several reviews with this topic. Furthermore, green synthesis in chemistry is nowadays one of the essential aspects to be taken into consideration in the development of novel products. In accordance with this feature, the MIP community more recently devoted considerable research and development efforts on eco-friendly processes. Among other materials, biomass waste, which is a big environmental problem because most of it is discarded, can represent a potential sustainable alternative source in green synthesis, which can be addressed to the production of high-value carbon-based materials with different applications. This review aims to focus and explore in detail the recent progress in the use of biomass waste for imprinted polymers preparation. Specifically, different types of biomass waste in MIP preparation will be exploited: chitosan, cellulose, activated carbon, carbon dots, cyclodextrins, and waste extracts, describing the approaches used in the synthesis of MIPs combined with biomass waste derivatives.
Highlights
IntroductionIts concepts are accepted in academic and industrial spheres on a worldwide basis, recognizing that the implementation of green chemistry strategies is beneficial both to lead to a cleaner and more sustainable world but that it is economically advantageous with many positive social effects [1,2,3,4,5]
This review provides an extensive overview on the use of different kind of biomass waste derivatives as backbone materials in Molecular Imprinting Polymer (MIP) preparation, pointing out the most recent works that developed greener analytical protocols of synthesis to reduce environmental pollution
A complete description of strategies to replace typical highly toxic chemicals generally required in MIPs, with natural polymers obtained from biomass wastes, such as chitosan, cellulose, or cyclodextrins, was made
Summary
Its concepts are accepted in academic and industrial spheres on a worldwide basis, recognizing that the implementation of green chemistry strategies is beneficial both to lead to a cleaner and more sustainable world but that it is economically advantageous with many positive social effects [1,2,3,4,5]. One of the aspects of green and sustainable chemistry that will be analyzed in this review is the valorization of biomass waste [6,7,8,9,10,11,12]. In the light of these considerations, one of the main objectives is to drastically reduce the environmental impact of waste with the scope to promote the concept for their recycling and transforming it into value added products
