Article Synopsis
- This study explored the grafting of a new monomer, Br-PS, onto sodium alginate (Alg) using free radical polymerization to create a novel material, poly (Br-PS)-g-Alg.
- Key parameters for the polymerization process, such as concentrations, duration, and temperature, were optimized, and the resulting polymer was characterized through various methods including FT-IR, H NMR, and SEM.
- The poly (Br-PS)-g-Alg showed effective cytotoxicity against specific cancer cell lines while maintaining selectivity, and it demonstrated potential for drug delivery applications, specifically for the controlled release of 5-fluorouracil.
In our current research, a new type of functional nanocomposites known as poly(methyl methacrylate/,-dimethyl aminoethylmethacrylate/()-2-cyano--cyclohexyl-3 (dimethylamino) acrylamide) [poly(MMA/DMAEMA/CHAA)] has been developed. These nanocomposites were created using microemulsion polymerization in conjunction with synthesized titanium dioxide (TiO), and vanadium pentoxide (VO) nanoparticles. To understand the physio-chemical characteristics of the poly(MMA/DMAEMA/CHAA) and the metal oxide nanoparticles (MOs) integrated within them, various analytical techniques were employed.
