“…Furthermore, in recent years, their applications extended to manufacturing optical and electronic materials. Plastic cups, bottles, bowls, food containers, and utensils used for microwaves are also synthesized with polymers (9,10). Epoxy resins protect the can from the inside; therefore, they can be a considerable source for the adulteration of food items due to direct contact (11,12).…”

Bisphenol A (BPA) is a synthetic chemical widely employed to synthesize epoxy resins, polymer materials, and polycarbonate plastics. BPA is abundant in the environment, i.e., in food containers, water bottles, thermal papers, toys, medical devices, etc., and is incorporated into soil/water through leaching. Being a potent endocrine disrupter, and has the potential to alter several body mechanisms. Studies confirmed its anti-androgen action and estrogen-like effects, which impart many negative health impacts, especially on the immune system, neuroendocrine process, and reproductive mechanism. Moreover, it can also induce mutagenesis and carcinogenesis, as per recent scientific research. This review focuses on BPA’s presence and concentrations in different environments, food sources and the basic mechanisms of BPA-induced toxicity and health disruptions. It is a unique review of its type because it focuses on the association of cancer, hormonal disruption, immunosuppression, and infertility with BPA. These issues are widespread today, and BPA significantly contributes to their incidence because of its wide usage in daily life utensils and other accessories. The review also discusses researched-based measures to cope with the toxic chemical.

“…The association, as well as the disassociation of the imprint, could happen in the plain diffusion through in and out of the sites. The approach is very useful in the process of preparing MIPs by simplifying and determining the availability of different monomers to interact with the type of template for any type of imprinting process [56]. This approach is also associated with some drawbacks, as the interactions of template monomers are usually managed through the equilibrium process.…”

Molecular imprinting polymers (MIPs) have been widely used to produce stable polymeric materials due to their highly selective binding sites to determine the analyte (target molecule) in food products. MIPs begin with a complex compound between the template molecule and the functional monomers that can be polymerized when there is a closely crossed link. MIPs left specific cavities after the removal of templates during washing, which complements the size and shape of the templates. The use of MIPs has contributed to novel advances in materials science, polymer science, natural science, and other multi-disciplinary systems. Optical chemical sensor is an exciting field in MIPs today due to comprehend the unique affirmation limit of associated polymers giving stable polymers with high molecular recognition capabilities. MIPs display a wide extent of relevance, incredible flexibility, security, and high selectivity; their internal affirmation districts can be explicitly gotten together with design molecules to achieve specific affirmation. This review covers the various achievements of sensors used in laboratory analyses. The advancement in the development of MIPs is evaluated with an accentuation on the preparation principle, the discovery process, the molecular recognition mechanism and future perspectives and challenges for MIPs in building an optical chemical sensor.

“…Molecularly imprinted polymers (MIPs) have become a research hotspot due to their superior selectivity over natural receptors, increased physicochemical stability and better selectivity [ 21 , 22 ]. Hamed E M et al have summarized the different production methods and the varied types of sensors that employed MIPs for Bisphenol A detection [ 23 ]. Nanomaterials with large surface areas are always modified on the rigid electrodes to construct the electrochemical sensors [ 24 ].…”

A flexible electrochemical sensor based on the carbon felt (CF) functionalized with Bisphenol A (BPA) synthetic receptors was developed. The artificial Bisphenol A receptors were grafted on the CF by a simple thermal polymerization molecular imprinting process. Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and electrochemical characterizations were used to analyze the receptors. Characterization results demonstrated that the Bisphenol A synthetic receptors successfully formed on the CFs surface. Because the synthetic receptor and the porous CFs were successfully combined, the sensor displayed a better current response once Bisphenol A was identified. The sensor’s linear range was determined to be from 0.5 to 8.0 nM and 10.0 to 300.0 nM, with a detection limit of 0.36 nM. Even after being bent and stretched repeatedly, the electrode’s performance was unaffected, demonstrating the robustness, adaptability and viability of installing the sensor on flat or curved surfaces for on-site detection. The designed electrochemical sensor has been used successfully to identify Bisphenol A in milk samples with satisfactory results. This work provided a promising platform for the design of implantable, portable and miniaturized sensors.
