Research Summary: Marine polysaccharide-based nanomaterials as a novel source of nanobiotechnologica
Research on marine polysaccharide-based nanomaterials is emerging in nanobiotechnological fields suchas drug delivery, gene delivery, tissue engineering, cancer therapy, wound dressing, biosensors, and watertreatment. Important properties of the marine polysaccharides include biocompatibility, biodegradabil-ity, nontoxicity, low cost, and abundance. Most of the marine polysaccharides are derived from naturalsources such as fucoidan, alginates, carrageenan, agarose, porphyran, ulvan, mauran, chitin, chitosan,and chitooligosaccharide. Marine polysaccharides are very important biological macromolecules thatwidely exist in marine organisms. Marine polysaccharides exhibit a vast variety of structures and arestill under-exploited and thus should be considered as a novel source of natural products for drug dis-covery. An enormous variety of polysaccharides can be extracted from marine organisms such as algae,crustaceans, and microorganisms. Marine polysaccharides have been shown to have a variety of bio-logical and biomedical properties. Recently, research and development of marine polysaccharide-basednanomaterials have received considerable attention as one of the major resources for nanotechnologicalapplications.
