Molecules, Journal Year: 2023, Volume and Issue: 28(6), P. 2798 - 2798

Published: March 20, 2023

The introduction of selective recognition sites toward certain heavy metal ions (HMIs) is a great challenge, which has major role when the separation species with similar physicochemical features considered. In this context, ion-imprinted polymers (IIPs) developed based on principle molecular imprinting methodology, have emerged as an innovative solution. Recent advances in IIPs shown that they exhibit higher selectivity coefficients than non-imprinted ones, could support large range environmental applications starting from extraction and monitoring HMIs to their detection quantification. This review will emphasize application for removal transition (including HMIs, precious ions, radionuclides, rare earth ions) aqueous solution by critically analyzing most relevant literature studies last decade. first part review, chemical components IIPs, main ion-imprinting technologies well characterization methods used evaluate binding properties are briefly presented. second part, synthesis parameters, adsorption performance, descriptive analysis solid phase various provided.

Over recent years, chronic wounds, caused by various factors including diabetics and burns, have represented the major challenge financial burden for both physicians patients. Traditional wound care strategies based on passive dressing are not capable of real-time monitoring timely treatment, which may result in overaggressive or conservative therapeutic options. To address these drawbacks, smart bandages with capabilities biomarkers diagnosing even implementing approaches to achieve efficient healing wounds attracted widespread research interests. The current frontier is embryonic phase towards a "closed-loop" management style. In this review, only technologies environment monitoring, but also mechanisms, materials characteristics platforms that promote discussed, while progress concept "theranostics" summarized. This review provides fundamental understanding biology, should be valuable desirable assessment status, medical intervention, expected facilitate evolution new generation preferable applications.

Synthesis and Characterization of Thermoresponsive Chitosan-graft-poly(N-isopropylacrylamide) Copolymers

Polymers, Journal Year: 2023, Volume and Issue: 15(15), P. 3154 - 3154

Published: July 25, 2023

Thermoresponsive chitosan-graft-poly(N-isopropylacrylamide) (CS-g-PNIPAAm) copolymers of different composition were synthesized by free-radical polymerization chitosan (CS) and N-isopropylacrylamide (NIPAAm) in aqueous solution using potassium persulfate (PPS) as an initiator. By changing the molar ratio CS:NIPAAm from 1:0.25 to 1:10 graft with a CS backbone amounts PNIPAM side chains prepared. The chemical structure obtained CS-g-PNIPAAm was confirmed FTIR 1H NMR spectroscopy. spectra also used calculate content attached PNIPAAm chains. Moreover, lower critical temperature (LCST) behavior assessed cloud point, differential scanning calorimetry particle size measurements. solutions containing ≥12 percent demonstrated LCST phase separation at around 29.0–32.7 °C. intensity thermoresponsiveness depended on increased increasing poly(N-isopropylacrylamide) moieties. thermoresponsive could be potentially applied drug delivery systems or tissue engineering.
