This work was conducted to study the potential of molecularly imprinted polymers (MIPs) for the removal of oestradiol at trace concentrations (1 ppm–1 ppb). An MIP synthesised with 17β-oestradiol as template was compared to non-imprinted polymers (NIP) synthesised under the same conditions but without template, a commercial C18 extraction phase and granulated activated carbon. At 1 ppb oestradiol was recovered by 98±2% when using the MIP, compared to 90±1, 79±1, and 84±2% when using the NIP, a C18 phase, or granulated activated carbon, respectively. According to these levels, the MIP was capable of producing an effluent with a quality 5–10 times higher than the other materials. The same levels of oestradiol recovery were achieved with the MIP when supplying 17β-oestradiol at 0.1 ppm. Phenolic compounds added as interferences bound less to the MIP than to the NIP, confirming the selectivity of the MIP. Oestradiol biodegradation was also demonstrated at high concentrations (50 ppm), showing the pollutants can be safely destructed after being enriched by molecular extraction. This study demonstrates the potential of molecular imprinted polymers as a highly efficient specific adsorbent for the removal of trace contaminants.

AbstractTechnology of molecularly imprinted polymers (MIP) has become very popular in recent decades. MIPs are primarily used in medical diagnostics, chromatographic separation and solid phase extraction (SPE); also as sensors and catalysts. In recent years there have been reported benefits of combining molecular imprinted polymers with additional features, e.g. magnetic properties, through the build-up of this type of material on magnetite particles (Magnetic Molecularly Imprinted Polymer – MMIP). This method produces a multifunctional material which has high selectivity and the ability to isolate the analyte from biological and environmental samples, allowing effective purification from such interferents as proteins and fats. This developing branch of new materials for the preparation and purification of complex sample matrices is an interesting alternative to materials routinely used to date, particularly with regard to the immunosorbents. This paper summarizes recent reports regarding MMIP preparation and their application for purification and isolation of compounds from biological matrices.

To establish a novel method for preparing molecularly imprinted polymers for Picroside I with better performance on TCM research contrast to previous studies, we have prepared novel surface molecular imprinted polymers (S-MIPs) using Picroside I as the template molecule, Acrylamide (AM) as the functional monomer, and silica gel as the carrier. The morphology of S-MIPs was characterized by scanning electron microscope (SEM) and its static adsorption capacity was measured by the Scatchard equation.

Molecular imprinted polymers are custom made materials with specific recognition sites for a target molecule. Their specificity and the variety of materials and physical shapes in which they can be fabricated make them ideal components for sensing platforms. Despite their excellent properties, MIP-based sensors have rarely left the academic laboratory environment. This work presents a comprehensive review of recent reports in the environmental and biomedical fields, with a focus on electrochemical and optical signaling mechanisms. The discussion aims to identify knowledge gaps that hinder the translation of MIP-based technology from research laboratories to commercialization.
