Chitosan, a deacetylated derivative of chitin, is a biodegradable cationic polymer. Chitosan can be a potential substitute for aluminum salts and synthetic polyelectrolytes in water treatment because it can: (1) avoid the health effects from residual aluminum (III) and synthetic polymers; (2) produce biodegradable sludge; and (3) reuse the crab shell. Chitosan can be modified with various pretr...

Considerable efforts have been devoted to control and maintain the sustained release of proteins. In this experiment, we used bovine serum albumin-fluorescein isothiocyanate (BSA-FITC) as a model protein to explore the potential utility of a chitosan and glycerol phosphate disodium salt (GP) hydrogel as a protein drug depot. The mixing of chitosan and GP solutions (0, 10, 20 and 30 wt%) formed ...

Chitosan treatment results in significantly lower plasma LDL-cholesterol concentrations. To 12 test the working mechanism of Chitosan, we measured plasma surrogate markers of cholesterol 13 absorption, synthesis, and degradation to bile acids corrected for cholesterol concentration (R_sterols). 14 One hundred sixteen obese subjects (BMI 31.7, range 28.1 – 38.9 kg/m2) were studied under Chitosan...

The effect of different gamma-ray irradiations on the functional groups and the mechanical properties of chitosan, collagen, and chitosan/collagen blend have been studied. Commercially available chitosan and extract of collagen from bovine tendon by acid dissolution method were employed. Chitosan, collagen and chitosan/collagen blend membranes were prepared using the solvent evaporation method....

Chitosan biopolymer represents an attractive alternative to other bio materials because of its significant physico– chemical behaviours. In order to improve chitosan’s performance, chemical modification has been carried out. Chemical modification that lead to the formation of chitosan derivatives, grafted chitosan and chitosan composites have gained much attention, extensively studied and widel...

Decellularized goat-lung scaffold was fabricated by removing cells from cadaver goat-lung tissue, and the scaffold was modified with chitosan/nanohydroxyapatite composite for the purpose of bone tissue engineering applications. MTT assay with osteoblasts, seeded over the chitosan/nanohydroxyapatite-modified decellularized scaffold, demonstrated significantly higher cell growth as compared to th...

Gold nanoparticles (AuNPs) had been synthesized with various molarities and weights of reducing agent, monosodium glutamate (MSG), and stabilizer chitosan, respectively. The significance of chitosan as stabilizer was distinguished through transmission electron microscopy (TEM) images and UV-Vis absorption spectra in which the interparticles distance increases whilst retaining the surface plasmo...

The aim of this study was to assess the effect of alginate-chitosan microcapsule on viability characteristics of Bacillus subtilis and the ability of B. subtilis/alginate-chitosan microcapsule to remove uranium ion from aqueous solution. The effects of particle size, chitosan molecular weight and inoculum density on viability characteristics were studied using alginate-chitosan microcapsule-imm...

In the present investigation chitosan has been chemically modified by treating with two different aldehydes like acetaldehyde and propionaldehyde to form Schiff's bases. Schiff's bases of chitosan with acetaldehyde and propionaldehyde were named as polymer A and polymer B, respectively. Fourier Transform Infra Red (FTIR) spectral data have confirmed the reaction carried out on chitosan. Drug fr...

The study was aimed at detecting the effects of Baycox and Chitosan on the development of coccidiosis on a broiler farm. The study involved 80 six-week-old-broiler chickens divided into two equal groups. Each group was divided into four subgroups: control (I); Baycox-treated (II); Chitosan treated (III); and Baycoxand Chitosan-treated (IV). Baycox was applied for 2 d in a concentration of 25 pp...
