Aldehydes Organic raw materials When the phosphate concentration was 2 mg P L(-1), the removal efficiency of phosphate maked 99 % and the residual concentration was only 10 μg P L(-1), which fulfills the USEPA touchstones for eutrophication prevention and control. In addition, after treatment by CS/TiO(2), the phosphate concentration of two sewage water samples diminished from 1 and 1 mg P L(-1) to <0 mg P L(-1), assembling the standard of level II water based on the Environmental Quality Standard of China (GB3838-2002). Ligand exchange and electrostatic interactions are mainly responsible for phosphate adsorption by CS/TiO(2) the CS/TiO(2) nanocomposites presented excellent antibacterial activity, which could avoid biofouling contamination caused by microorganisms. gaining from the above vantages, the as-projected CS/TiO(2) nanocomposite has great potential as a bio-finded antibacterial adsorbent for phosphate capture or removal from wastewater.Engineered Injectable Cell-Laden Chitin/Chitosan Hydrogel with Adhesion and Biodegradability for Calvarial Defect Regeneration.Trade-off of high-strength and dynamic crosslinking of hydrogels rests an enormous challenge. propeled by the self-healing property of biological tissues, the strategy of combining multiple dynamic bond mechanisms and a polysaccharide network is nominated to fabricate biomimetic hydrogels with sufficient mechanical strength, injectability, biodegradability, and self-curing property for bone reconstruction engineering. Stable acylhydrazone bails gifted hydrogels with robust mechanical strength (>10 kPa). The integration of dynamic imine bonds and acylhydrazone alliances optimised the reversible characteristic to protect the cell during the injection and mimicked ECM microenvironment for cell differentiation as well as rapid adapting bone defect area due to the slow enzymatic hydrolysis kinetics of chitosan and the self-curing holdings of resulting meshs, hydrogels exhibited a satisfactory biodegradation period (>8 workweeks) that highly touchs with bone regeneration rBMSC-laden hydrogels showed splendid osteogenic induction and bone reconstruction without prefabrication scaffolds and incubation, certifying tremendous potential for clinical application. This work purports an efficient strategy for the construction of a low-cost multifunctional hydrogel, making polysaccharide-finded hydrogels as the optimal carrier for enabling cellular offices in bone repair.Greater efficiency of polyherbal drug capsulised biosynthesized chitosan nano-biopolymer on diabetes and its complicatednessses.Diabetes is a highly complex disease that has an adverse impact on the livings of mortals, and the current musics used to manage diabetes have obvious side gists. Medicinal plants, on the other hand, may serve as an alternate source of anti-diabetic drugs. A polyherbal combination has a higher and more extensive therapeutic potential than a single herb due to deterioration during the absorption process, the usage of this drug still generates inadequate outcomes. Encapsulation of polyherbal drug with chitosan nanoparticles is one of the key ways to solve this problem due to its biocombatibilty, slow and placed drug delivery characteristics. In the present study, the chitosan was derived from prawn shell and the chitosan nanoparticles had been developed by ionic-gelation method. The anti-diabetic polyherbal drug (Andrographis paniculata, Andrographis alata, Adhatoda zeylanica, Gymnema sylvestre, Syzygium cumini, and Justicia glabra) was capsuled with a bio-derived chitosan biopolymer. The drug loading efficiency was about 85 %. The chemical and physical props of the chitosan and drug-diluted chitosan nanoparticles had been canvased by FT-IR absorption, XRD, SEM, TEM and EDAX analysis. The antidiabetic efficiency, hepatoprotective activity and antihyperlipedimic activity of the chitosan nanoparticles, polyherbal drug and polyherbal drug encapsulated with chitosan nanoparticles were valued in a group of rats.
