Title: A historical review on silver nanoparticles (AgNPs) synthesis for different leaf, vegetative and plant extracts

While frequently described as being 'silver' some are composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. It was found that the bacterium Lactobacillus fermentum created the smallest silver nanoparticles with an average size of 11.2 nm. It was also found that this bacterium produced the nanoparticles with the smallest size distribution and the nanoparticles were found mostly on the outside of the cells. Silver has a long history of its usage in different forms and for different purposes. Nanoparticles have unique properties due to their small size.The surface area to volume ratio is 0.00000008, a factor of 7,500,000 less than 10 nm nanoparticles. While high surface area to volume ratios is important for applications such as catalysis, the actual properties of silver are different at the nanoscale.Read More
