Chitosan is a deacetylated derivative of chitin. This polysaccharide has received a great attention due to its biocompatibility, low toxicity, biodegradable, furthermore can be used into different shapes, such as beads, hydrogels, powders, films and membranes. Chitosan hydrogels may be formed by ...

Biocompatibility of thermosensitive chitosan-based hydrogels: an in vivo experimental approach to injectable biomaterials 来自 NCBI 喜欢 0 阅读量: 230 作者:G Molinaro,JC Leroux,J Damas,A Adam 摘要: Chitosan, an amino-polysaccharide obtained from the alkaline deacetylation of chitin, presents an ...
During the last decade, hydrogels prepared from biodegradable polymers, especially natural biodegradable polymers, have been studied extensively for drug delivery and tissue engineering. Chitosan, one of the most abundant natural polymers, is a good candidate and the most widely studied polymer for biome...
Compared with CS, quaternized chitosan (QCS) has better antibacterial properties and solubility; it is also more conducive to the formation of injectable hydrogels [32]. Hyaluronic acid (HA), a member of the glycosaminoglycan family consisting of a basic unit of glucuronic acid and N-acetyl-...

Interestingly, the drug release profile of Cs/PAA hydrogels can be changed depending on the ambient pH, which makes these materials suitable for colon-targeted controlled drug delivery. However, morphological structures of these hydrogels were dense and compact with few pores, thus lowering their ...
