SUMMARY AND CONCLUSION 6.1 Summary Silver nanoparticles are nanoparticles of silver composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Various shapes and sizes of nanoparticles are synthesized by physical‚ chemical and biological methods. The Chrysophyllum canito leaf extracts were used for silver nanoparticles synthesis. In this study utterly revealed the best milli molar concentrations of silver nanoparticles synthesis in diverse solvents such

BIOPOL Biopol is a biopolymer that is an environmentally friendly biodegradable plastic made from renewable resources (made naturally in plants from starch and glucose). Biopol is the brand name for a group of biopolymers often called PHAs or PHBs. The continual use of petroleum to make polymers for plastic will eventually run out and hence Biopol was introduced as a polymer replacement for petroleum. It is made from an organic substance known as Alcaligenes eutrophus which is a microorganism.
