The results demonstrated that at 0% w/v CS, 0% w/v ALG, pH 4, and absence of CaCl(2) , crocin was diluted into CS/ALG NPs with EE% and LE% of 91% and 27%, respectively.  chitosan price  contracted the particle sizings (PSs) up to 100 nm, and freeze-dried NPs reproduced the atoms with average size of 90 nm. raking electron microscopy (SEM) was successfully used to characterize the structure and morphology of freeze-dried NPs, corroborating very fine NPs inducing sizes less than 100 nm. Crocin charged into NPs depicted higher stability in simulated gastric pH 2 compared to free crocin (2% and 7% degradation at 60 min, respectively) a pH-dependent sustained crocin release was observed 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 materials and equipments utilized in current research provide the possibility to industrial scale up of the Crocin nanoparticles.Chemical functionalization of Chitosan biopolymer with diacetyl monoxime for heightened Cr(VI) removal from aqueous metiers.Hexavalent chromium is recognised for high toxicity as well as carcinogenicity and leads to contamination of water consistences through various anthropogenic activenessses. Chitosan biopolymer has throttled adsorption capacity towards this toxicant. In order to boost hexavalent chromium adsorption, diacetylmonoxime was used to modify thiolated chitosan. The ensuing material was extensively characterized utilising Fourier Transform Infrared, Energy Dispersive X-ray, Scanning Electron Microscopic and X-ray Diffraction investigations. To comprehend the adsorption mechanism in better way, various adsorption isotherms like Langmuir and Freundlich were inquired.

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. The results pointed that, 98 ± 0 % adsorption takes 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. concording to the Langmuir monolayer isotherm, the material was discovered to have Cr(VI) adsorption capacity of 430 mg g(-1) under optimised operational preconditions. Adsorption of Cr(VI) proceeds with pseudo-second-order kinetics. Because of the increasing unpredictability at interaction sites, it was finded that adsorption efficiency lessened with rising temperature. Negative values of Gibbs free energy and enthalpy leveled towards the spontaneous and exothermic behaviour of the adsorption process. To find out if the material was suitable for greater sample books, column examinations were behaved that showed excellent solutions for continuous column adsorption experiments.

Chemoselective modification of chitosan with arginine and hydroxyproline: Development of antibacterial composite cinemas for wound healing coatings.This study searched the enhancement of chitosan for wound dressing coverings through selective functionalization with arginine and hydroxyproline amino acids, compounded with polyvinyl pyrrolidone (PVP) and polyvinyl alcohol (PVA) in composite movies. The research hired chemoselective amino acid grafting accompanyed by solution spewing to fabricate the composite stuffs. Fourier transform infrared (FTIR) analysis asserted 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.  chitosan supplement benefits  certifyed exceptional attributes, attaining maximum tensile strength of approximately 55 MPa and tumescing ratio of about 400 %.
