Marine biofouling is a worldwide problem affecting maritime industries. Global concerns about the high toxicity of antifouling paints have highlighted the need to develop less toxic antifouling coatings. Chitosan is a natural polymer with antimicrobial, antifungal and antialgal properties that is obtained from partial deacetylation of crustacean waste. In the present study, nanocomposite chitos...

We describe a simple way to create patterns of ‘‘soft’’ biomolecular nanostructures such as vesicles on ‘‘hard’’ surfaces such as gold. The key to our approach is the use of an amphiphilic biopolymer as an ‘‘interconnect’’ or tether. The polymer is hydrophobically modified chitosan (hm-chitosan), which is obtained by covalently attaching alkyl tails to the backbone of chitosan. We electrodeposi...

the chitosan nanoparticles used widely as a drug delivery systems recently. in the present study the echis carinataus snake venom loaded chitosan nanoparticles were prepared based on ionic gelation of tripolyphosphate and chitosan. the nanoparticles physicochemical characteristics, stability and biological activity of encapsulated venom were studied. the particles were spherical in shape and th...
