Synthesis and characterization of chitosan-based hydrogels

Photocrosslinked layered gelatin-chitosan hydrogel with graded compositions for osteochondral defect repair

“…It was reported that most of hydrogels showed a level of cell viabilities about 80 % [46]. In comparison, the cell viabilities in the extracts from different layers of the Gtn-CS hydrogels prepared in this study were higher than 80 %, better than those of some previous photocrosslinked hydrogels [15,43].…”

Curcumin nanoparticles loaded hydrogels protects against aflatoxin B1-induced genotoxicity in rat liver

“…The International Agency for Research on Cancer (IARC) has classified AFB 1 as a group one carcinogen (IARC, 1987). Hydrogels (Hgs) are three-dimensional networks of hydrophilic polymers not soluble but swellable in water (Li et al, 2009). These polymers have attracted extensive attention as intelligent materials in biomedical fields as drug delivery, wound dressing and tissue engineering as well as surgical aids because of their biocompatibility and resemblance to biological tissues (Jiang et al, 2006).…”

Preparation and characterization of N-heterocyclic chitosan derivative based gels for biomedical applications

“…Unlike other polysaccharides, chitosan is polycationic in nature [1] and it is composed of glucosamine units and Nacetylglucosamine units. The principal derivative of chitin [2][3][4], chitosan is a highly specialized biopolymer found in the cuticles of arthropods, endoskeletons of cephalopods, mushrooms and fungi [5]. Chitosan has been well documented with some advantageous characteristics, including chemical modification, antimicrobial activity, biocompatibility, biodegradability, hydrophilicity, nontoxicity, and nonantigenicity as well as bioadherence and cell affinity [6][7][8][9][10].…”
