Summary: In this study, a new method for the preparation of noncovalent enzyme nanogels (ENGs) was developed, utilizing a heterobifunctional, photocleavable monomer. The stability of the enzyme in the noncovalent nanogels was found to be higher compared to the enzyme alone, indicating the potential usefulness of this method for enzyme stabilization.

Summary: In this study, a new type of porous absorbent (SI-scd) composed of SiO2 and ionic liquid [C(4)py][DCA] was successfully synthesized via solid surface immobilized method, showing a large surface area (100.25 m(2).g(-1)). SI-scd exhibited high adsorption capacity (46.003 mg.g(-1) at 298 K) for As (III), outperforming commercial absorbents. Moreover, SI-scd demonstrated excellent adsorption kinetics, good stability, and selectivity in wastewater treatment.

Summary: The main obstacles in adopting solvent-based CO2 capture technology from power plant flue gases at the industrial scale can be overcome using new green and more stable ionic liquids as solvents. In this study, phosphonium chloride-based ILs immobilized on hydrophobic porous supports were tested for CO2 permeability and selectivity, with PTFE support-based SILM performing the best. This research suggests that phosphonium chloride-based ILs could be better solvent candidates for CO2 removal from large volumes of flue gases.

Summary: This study presents a novel method for immobilizing chiral (S)-1,1'-Bi-2-naphthol ligand (BINOL) onto amine functionalized mesoporous silica nanoparticles (MSNs) via a linker, without the use of protecting or deprotecting groups. The resulting ruthenium complex, Ru-BINOL-AP@MSNs, was successfully synthesized and verified using various analytical techniques. The synthesized catalyst demonstrated high activity and enantioselectivity in the asymmetric transformations of chiral alcohols. Additionally, the catalyst showed excellent recyclability and maintained its effectiveness after five consecutive cycles.

Summary: The commercialization of chiral drugs is a growing concern in pharmacology due to the potential issues with the pharmacological activities of enantiomers in racemates. This study aimed to develop a platform for the resolution of propranolol using chiral selectors in biphasic systems, with a focus on enantioselective liquid-liquid extraction (ELLE) systems. The most efficient biphasic system identified involved 1,2-dichloroethane-water, dipentyl-L-tartrate, and boric acid as chiral selectors, achieving an enantioselectivity of 2.54.

Summary: Chronic wounds show high levels of cell-free deoxyribonucleic acid (cfDNA), leading to prolonged inflammation and non-healing wounds. Nanogels derived from chitosan and poly{2-[(acryloyloxy)ethyl]trimethylammonium chloride} were found to scavenge cfDNA efficiently due to their positive charge and network structure. The enhanced cfDNA scavenging ability and biocompatibility of the nanogels make them a promising component for chronic wound dressings.
