background silver has been used from ancient times by humans, and recently nanoparticles of silver have been used in many aspects of human life including as a potent antibacterial agent. objectives in the current study a completely green method to prepare silver nanoparticles is reported. two types of starches (potato and corn starches) were used to produce and stabilize silver nanoparticles. a...

Background: Due to the importance of investigating nosocomial infections and drug resistance in bacteria causing these infections, the use of herbs can be very helpful in treatment. In the present study, the effect of silver nanoparticles obtained from portulaca oleracea extract on bacteria causing nosocomial infections and effective parameters in the synthesis of these nanoparticles were inves...

The review article summarizes the applications of silver nanoparticles for diverse sectors. Over the decades, nanoparticles used as dignified metals such as silver exhibited distinctive characteristics basically correlated to chemical, physical and biological property of counterparts having bulkiness. Numerous studies reported that Nanoparticles of about 100nm diameter play a crucial role in wi...
