Due to the various properties shown by these composites, in comparison to individual particles, the studies that are related to the understanding and characterization of these materials have gained much importance. nanoparticles are warming at room temperature to form metal colloids, in this stage, depending on the metal concentration i.e. metal type, organic solvent and delay time to stabilize the colloidal nanoparticles, the nanoparticles aggregation produce in different shapes (spherical, clusters, fractals, etc.),. The SMAD technique due to reducing and stabilizing metal nanoparticles in a polymer matrix at the time of synthesis, avoiding metal agglomeration and oxidizing of metal nanoparticles does not produce salt. There is great concentration on these compounds as they can be used in medicine as antibacterial coatings, due to the biocidal action of Au nanoparticles (AuNps). Undeniably, numerous selective homogeneous catalysts from nanoparticles have been reported but the only feature is the ability of the polymer chain to protect and stabilize the metal particles from oxidation, therefore, the penetration of the reagents for the desired catalytic reactions is possible.}, keywords = {Aggregation of Gold Nanoparticles,nano-biosensor,Dissociation of Gold Nanoparticles,Laser Irradiation,Visual detection,Immunoassay}, url = {http://www.ajchem-a.com/article_93679.html}, eprint = {} }
