The outcomes indicated that at 0% w/v CS, 0% w/v ALG, pH 4, and absence of CaCl(2) , crocin was debased into CS/ALG NPs with EE% and LE% of 91% and 27%, respectively. Ultrasonication reduced the particle sizes (PSs) up to 100 nm, and freeze-dried NPs multiplyed the motes with average size of 90 nm. Scanning electron microscopy (SEM) was successfully used to characterize the structure and morphology of freeze-dried NPs, substantiating very fine NPs inducing sizings less than 100 nm. Crocin charged into NPs showed higher stability in shamed gastric pH 2 equated to free crocin (2% and 7% degradation at 60 min, respectively) a pH-dependent sustained crocin release was keeped with faster release at pH 2 the very small PS along with high encapsulation efficiency and stability can enhance crocin oral bioavailability urinating CS/ALG nanovehicles assuring as an effective delivery system. PRACTICAL APPLICATION: Crocin as a functional component of Saffron is not sufficiently stable in gastrointestinal tract and its absorption is not complete. Chitosan/Alginate nanoparticles can encapsulate it efficiently, protect it and enhance its absorption orally.

The availability and simplicity of the stuffs and equipments engaged in current research provide the possibility to industrial scale up of the Crocin nanoparticles.Chemical functionalization of Chitosan biopolymer with diacetyl monoxime for enhanced Cr(VI) removal from aqueous metiers.Hexavalent chromium is known for high toxicity as well as carcinogenicity and leads to contamination of water consistences through various anthropogenic activities. Chitosan biopolymer has binded adsorption capacity towards this toxicant. In order to boost hexavalent chromium adsorption, diacetylmonoxime was used to modify thiolated chitosan. The leading material was extensively characterized utilising Fourier Transform Infrared, Energy Dispersive X-ray, Scanning Electron Microscopic and X-ray Diffraction probes. To comprehend the adsorption mechanism in better way, various adsorption isotherms like Langmuir and Freundlich were investigated.

In order to maximize the efficiency of adsorbent, response surface approach was used to optimize the several adsorption parameters, such as pH, adsorbent dose, adsorbate concentration, duration, and temperature.  fucose price  betokened that, 98 ± 0 % adsorption trains place at pH 5 with an adsorbent dosage of 20 mg and an adsorbate concentration of 20 mg L(-1) at 298 K temperature within a short period of 60 min. alloting to the Langmuir monolayer isotherm, the material was observed to have Cr(VI) adsorption capacity of 430 mg g(-1) under optimised operational preconditions. Adsorption of Cr(VI) gos with pseudo-second-order kinetics. Because of the increasing unpredictability at interaction sites, it was finded that adsorption efficiency lessened with lifting temperature. Negative values of Gibbs free energy and enthalpy channelized towards the spontaneous and exothermic behaviour of the adsorption process. To find out if the material was suitable for greater sample bulks, column exams were conducted that indicated excellent results for continuous column adsorption experimentations.

Chemoselective modification of chitosan with arginine and hydroxyproline: Development of antibacterial composite cinemas for wound healing coatings.This study explored the enhancement of chitosan for wound dressing coverings through selective functionalization with arginine and hydroxyproline amino Zens, combined with polyvinyl pyrrolidone (PVP) and polyvinyl alcohol (PVA) in composite films. The research employed chemoselective amino acid grafting followed by solution casting to fabricate the composite fabrics. Fourier transform infrared (FTIR) analysis sweared successful chitosan modification through the presence of a carbamate bond at 1719 cm(-1) and an amide bond shift from 1660 to 1680 cm(-1), with nuclear magnetic resonance (NMR) analysis catering additional confirmation. The composite films demonstrated exceptional properties, attaining maximum tensile strength of approximately 55 MPa and tumescing ratio of about 400 %.
