ABSTRACT: Silver nanoparticles are nanoparticles of silver which are in the range of 1 and 100 nm in size. Silver nanoparticles have unique properties which help in molecular diagnostics‚ in therapies‚ as well as in devices that are used in several medical procedures. The major methods used for silver nanoparticle synthesis are the physical and chemical methods. The problem with the chemical and physical methods is that the synthesis is expensive and can also have toxic substances absorbed onto

concentration affect the activity of the enzyme catalase? Hypothesis: By increasing the concentration of FeSO4‚ there will be a decrease in the activity of the enzyme catalase because the Iron (ii) in the metallic ion will act as an inhibitor during the catalysis of the hydrogen peroxide into O2 and H2O. Introduction: We rely on oxygen to provide us with energy (ATP) and go through all the phases of aerobic respiration. However‚ oxygen can be harmful to humans and can cause problems if not carefully regulated

Latest Invention: Tea Bag that Uses Nanotechnology to Clean Drinking Water One of the latest inventions developed by researchers from Stellenbosch University in South Africa is a one of a kind "tea bag" that makes use of nanotechnology to clean drinking water‚ making it free from contaminants and bacteria. It would be interesting to note that the "tea bag" is made of the same material that is used to make the actual tea bags. The only difference is that in the Stellenbosch researchers’ invention
