dc.description.abstractCross-linked polymeric network containing microgel was synthesized by using Linoleic acid as monomer, BIS as crosslinker and SDS as stabilizer by using precipitation polymerization reaction method in an aqueous medium. APS was used as an initiator for the polymerization process. This synthesized microgel was further used for the synthesis of hybrid microgel by introducing cobalt nitrate salt and then sodium borohydride as a reductant. Cobalt ions were converted into a cluster of cobalt metals which are called cobalt nanoparticles. Characterizations of these pure microgels and cobalt nanoparticles loaded hybrid microgels were done by FTIR spectrophotometer and scanning electron microscope (SEM) techniques. Results showed that cobalt nanoparticles were formed within the cross-linked polymer network of microgels. Results also showed that nanoparticles of cobalt metals having a diameter of 200 nm and 10 micrometer in the microgel network. Antibacterial activity of microgels and hybrid microgels was checked against both gram-positive and gram-negative bacteria. With the addition of inoculum, ppm solutions and nutrient broth to the test tubes, after 24 hours the test tubes become milky and the color of the solution becomes blurred.
