Popis: Methotrexate is one of the most popular and safe anti-inflammatory drugs which is an antifolate-type antimetabolite and is used as an anticancer drug. In this study, oppositely charged chitosan and fucoidan have been non-covalently bonded using their electrostatic interactions with the methotrexate drug loaded into these nanoparticles. Fucoidan is obtained from marine algae which are composed of l-fucose and sulfate groups in various types of brown seaweeds; whereas chitosan is a naturally occurring biopolymer obtained through the N-deacetylation of chitin. Depending on the fucoidan / chitosan (F / C) weight ratio, three distinct nanoparticles (1F / 1C; 3F / 1C; 5F / 1C) are synthesized and characterized. Nanoparticles were prepared using cross linkers EDC and NHS at a constant pH to reduce the conjugate size. The prepared conjugates were characterized for their size and zeta potential using DLS analysis and the functional groups were analysed using FTIR. DLS results proclaimed that there was size reduction in particle size with cross linker and without the drug methotrexate. The 5:1 F/C nanoparticles was seen to be 441.5 nm, the difference being considerable larger in the 5:1 formulation. Hence for further analysis 5:1 F/C nanoparticles were preferred. Maximum entrapment efficiency was observed in 5:1 F/C nanoparticle with and without cross linkers. To understand the structural morphology of nanoparticles electromagnetic magnification like SEM and TEM were taken in account.
