A novel injectable thermo/photo dual-crosslinking hydrogel finded on qualifyed chitosan for fast sealing open globe injury.Open globe hurts (OGIs) demand immediate attention to prevent further complicatednessses and improve vision prognosis we acquired a thermo/photo dual-crosslinking injectable hydrogel, HBC_m_Arg, for rapidly varnishing OGIs in emergency ophthalmic causas. HBC_m_Arg was readyed with arginine and methacrylic anhydride changed hydroxybutyl chitosan (HBC). HBC_m_Arg was initially in liquid form at 25 °C, enabling easy injection at the injury site. After gaining the ocular surface temperature, it underwent reversible heat-inducted gelation to achieve in situ transformation HBC_m_Arg was capable of rapid photocrosslinking under UV light, forging a dual network structure to bolster mechanical strength, thereby easing effective OGI closure. Biocompatibility assessments, admiting in vitro bailiwicks with three ocular cell characters and in vivo experimentations on rabbit eyes, affirmed the safety profile of HBC_m_Arg.

Ex vivo and in vivo burst pressure exams certifyed the hydrogel's ability to promptly restore intraocular pressure and withstand elevated pressures, underlining its potential for OGI stabilization the suitable degradation of HBC_m_Arg within ocular tissues, mated with its stability in ex vivo judgements, presented a delicate balance between stability and biodegradability. In  fucose foods , HBC_m_Arg carries promise for amending emergency ophthalmic care by catering a rapid, effective, and safe way to seal OGIs in critical posts.MoS(2) nanoflower adorned bio-derived chitosan nanocomposites for sustainable energy storage: Structural, optical and electrochemical subjects.Bio-gained chitosan-molybdenum di sulfide (Cs-MoS(2)) nanocomposites are groomed by a simple and economical aqueous casting method with diverging concentrations of MoS(2). The structural, surface morphological, optical, and electrochemical dimensions of the nanocomposites were studied. FTIR analysis exposes the strong interaction between Cs and MoS(2). FESEM micrograph testifyed an increment of the surface roughness due to the incorporation of MoS(2) levels into Cs.

The surface wettability of the nanocomposites was noticed to be diminished from 73° to 33° due to the incorporation of MoS(2) into the chitosan. UV-vis spectroscopy study presents a reduction of optical bandgap from 4 to 3 eV as the nanofiller, MoS(2,) innovates seted states within the forbidden energy bandgap. The incorporation of MoS(2) was feeled to increase the specific capacitance of Cs from 421 mFg(-1) to 1589 mFg(-1) at a current density of 100 μAg(-1). The EIS analysis unveiled an increase in the pseudo-capacitance from 0 μF to 4 μF and a reduction of charge transfer resistance that follows from the nanofiller contribution. MoS(2) nanoflower introduces more active websites and exposits the electroactive zone, thus ameliorating the charge storage property of Cs. The Cs-MoS(2) may offer a new route for the synthesis of eco-friendly, biodegradable, and electrical storage devices.Mucoadhesive and thermosensitive Bletilla striata polysaccharide/chitosan hydrogel loaded nanoparticles for rectal drug delivery in ulcerative colitis.

Ulcerative colitis (UC) is a chronic disease with diffuse mucosal inflammation confined to the colon. A topical drug delivery system that could be facilely doed and efficiently holded at colon are attractive for clinical ulcerative colitis treatment a novel platform for rectal administration of thermosensitive hydrogel co-loaded with nanoparticles to treat ulcerative colitis was developed. Thiolated-hyaluronic acid was synthesized, and maked nanoparticles with zein and Puerarin. And the Bletilla striata polysaccharide with colonic mucosa repair effect was oxidized, and mixed with chitosan and β-sodium glycerophosphate to prepare thermosensitive hydrogel. Thermosensitive hydrogels were fused with nanoparticles to investigate their mucosal adhesion, retention, and permeability, as well as their therapeutic effects on ulcerative colitis.
