Marine polysaccharides for drug delivery in tissue engineering

Fucoidan in Pharmaceutical Formulations: A Comprehensive Review for Smart Drug Delivery Systems

“…The physiological pH varies along the gastrointestinal tract and, most importantly, it varies distinctly between healthy cells and tumor cells. Tumor cells possess acidic pH compared to normal cells due to their poor lymphatic drainage and high accumulation of waste product [ 23 , 24 ]. For any polymer to have a pH response, it should have ionizable functional groups interacting with the surrounding medium.…”

Current Status of Marine Animal Derived Polysaccharides in Sustainable Food Packaging

“…38,39 Modern research efforts have been directed toward the alteration of chitosan films with the aim of enhancing their mechanical and barrier characteristics. 40,41 The combination of chitosan with other natural polymers, such as alginate or pectin, has been reported to augment its properties. 42,43 The utilization of hyaluronan-based packaging has attracted significant interest as a prospective substitute for synthetic packaging materials.…”

“…Marine animals are a rich source of polysaccharides, namely chitosan, hyaluronan, chondroitin sulfate, and gelatin. , The efficacy of chitosan-based packaging in maintaining the quality and prolonging the shelf life of diverse food items, such as fruits, vegetables, meat, and seafood, has been reported. , Modern research efforts have been directed toward the alteration of chitosan films with the aim of enhancing their mechanical and barrier characteristics. , The combination of chitosan with other natural polymers, such as alginate or pectin, has been reported to augment its properties. , The utilization of hyaluronan-based packaging has attracted significant interest as a prospective substitute for synthetic packaging materials. , The film-forming properties of hyaluronan films, coupled with their high water-absorbing capacity, make them an appropriate choice for implementation in food packaging applications. , Chondroitin sulfate has also been explored as a potential natural polymer for food packaging. Chondroitin sulfate films have been shown to have good barrier properties against moisture and oxygen, as well as good mechanical properties. , The utilization of gelatin as a potential natural polymer for food packaging has been subject to extensive research. , The film-forming properties of gelatin films are admirable, and they exhibit satisfactory barrier properties against oxygen and moisture. , …”

Biocompatibility analysis of high molecular weight chitosan obtained from Pleoticus muelleri shrimps. Evaluation in prokaryotic and eukaryotic cells

“…Particularly, marine-derived polysaccharide have attracted attention for their wide usefulness in the biotechnological field [ 8 ]. Oceans contain several marine organisms, including algae, animals and plants, from which diverse polysaccharides with useful properties can be obtained [ 9 , 10 ]. Ever since ancient time, there are several attempts to reduce the volume of marine waste material with the aim to turn it into useful products [ 11 ].…”
