Synthesis of bio nano particles with special reference to gold and silver metal

Synthesis of phytobionanoagents has become one of the most popular technologies applied in all areas of sciences. Metal nanoparticles produced from plant extract have great applications in the biomedical and physiochemical field. These are produced by nanotechnology and at present have received global attention due to their extensive role in antimicrobial activity. Plant extract and their effect on microorganism has been extensively studied as convenient nano-agents for synthesis of metal nanoparticles and recognized as a green and efficient way for further exploiting antimicrobial agent. The development of multidrug resistant microbial strains and the appearance of strains which reduced susceptibility to antibiotics are continuously increasing. The problem of multidrug resistance promotes to search for new antimicrobial substances from various sources like medicinal plants. In present study focused on biological synthesis of phyto gold and silver nanoparticles through plant extract. (C) 2018 Elsevier Ltd. All rights reserved.
