“…Generally, Cd is capable of forming tetra or hexa coordinated complexes . The amino and hydroxyl groups on CTS chain are possibly involved for the uptake of Cd through formation of coordinated complex . The schematic representation of the imprinted cavity of DMIP along with the 4HBA and Cd is presented in the Figure .…”

“…Generally, municipal/domestic wastewater often contains contaminants such as pharmaceutical compounds and heavy metals . Salicylic acid and Cd can enter into the aquatic environment through various sources such as the pharmaceutical industry, human and veterinary drugs, paper and cosmetic industries, mining, smelting, usage of phosphate fertilizers, use of activated sludge from wastewater treatment plant for agricultural purpose, and various industries like plating, pigments, plastics, and Ni‐Cd batteries.…”

Ion cum molecularly dual imprinted polymer (DMIP) was synthesized for the simultaneous removal of salicylic acid (SA) and cadmium (Cd) by suspension polymerization method using chitosan (CTS) as functional polymer, epichlorohydrin as cross-linker, and 4-hydroxy benzoic acid (4HBA) as well as Cd as organic and inorganic templates, respectively. Use of the dummy template 4HBA during the synthesis of DMIP had the advantage of creating imprinted cavities in DMIP, which depicted good uptake for SA. Scanning electron microscopy and Fourier transform reported on the removal of both organic and inorganic pollutants simultaneously. Thus, attention needs to be given on developing more efficient method for removal of organic and inorganic pollutants simultaneously. 1-5In recent years, molecularly imprinting technique has gained much attention because it is a simple and convenient method to develop synthetic polymers showing high affinity towards the targeted analyte.It involves the formation of prepolymerisation complex between the template and functional monomer through covalent or noncovalent interaction in the presence of cross-linking agent. After polymerisation, template molecule is removed using suitable extracting solvent leaving behind memory sites that are complementary to template molecule. 6-10The super cross-linked nature of molecularly imprinted polymers (MIPs)imparts it high physical and chemical stability. In addition, MIPs can be reused without remarkable decrease in their binding capacity. 10-12Ion imprinting technique is a branch of MIP, widely used for synthesizing materials that are capable of recognizing metal ions. Ion imprinted polymers are highly cross-linked polymers synthesized in the presence of metal ion as the template. The template ion is then subsequently removed to get the ion imprinted polymers showing high selectivity towards targeted metal ion. 13,14Dual template imprinting can have several advantages over the conventional technique involving single template.

“…Carboxymethyl chitosan was formed to increase the physical and chemical properties of chitosan as researchers found that NPs were able to selectively release insulin throughout the intestinal medium in vivo, not simply protecting the stomach. (Aibani et al, 2021;Rahangdale et al, 2017;Rahangdale & Kumar, 2018).…”

The goal of this study was to see how effective subcutaneous (SC) insulin is and two different types of oral insulin‐loaded nanoparticles (INS) including carboxymethyl chitosan nanoparticles (CMCNPs) and gold nanoparticles (AuNPs) separately and compare their effects on glucokinase, pyruvate kinase gene expressions, and other parameters in diabetes type one male Wistar rats. Seven groups of ten male Wistar rats for each group were formed at random including four control groups (n = 10) and three treatment groups (n = 10). The control groups consisted of four control groups (10 rats for each) and three treatment groups (10 rats for each). Normal control rats were not given any treatment, as were diabetic rats that were not given any treatment, and diabetic rats that were given oral nanoparticles (CMCNPs and AuNPs). Diabetic rats were given subcutaneous insulin, oral insulin‐loaded carboxymethyl chitosan nanoparticles (INS‐CMCNPs), and oral insulin‐loaded gold nanoparticles (INS‐AuNPs). The rats were treated for the final 3 weeks of the experiment, which lasted 4 weeks. CMCNPs and AuNPs presented a promising effect on pyruvate kinase and Glucokinase gene expressions compared to subcutaneous insulin. We also discovered that conjugating insulin to CMCNPs and AuNPs protects them from the insulin‐degrading enzyme, which offers managed bioavailability. Furthermore, we investigated the effects of CMCNPs and AuNPs on several parameters and discovered that both have a significant effect in vivo, which enables glucose level regulation, and improves patient organ activity for better glucose consumption. Practical applications In this paper, we discussed the effect of oral INS‐CMCNPs and INS‐AuNPs, and compared their effects on Glucokinase and pyruvate kinase gene expressions and other biochemical parameters in diabetes type one male Wistar rats. On the other hand, we investigated the impact of oral INS and subcutaneous insulin separately on the same parameters and their effect on the histology of the liver and pancreas of diabetic rats. According to our research, as we discussed the different mechanisms of INS‐CMCNPs and INS‐AuNPs, they presented a promising effect compared to SC insulin. They can be used to keep oral insulin safe from the environment of the gastrointestinal system to overcome all the barriers, improve the therapeutic, and clinical outcomes of insulin by maintaining its desired concentration inside the body, ending the panic of the patient from receiving insulin by the SC injection by increasing his satisfaction with receiving accurate oral insulin doses.
