Synthesis of Silver Nanoparticles Using Novel Chemical Solution Method as Antibacterial Applied on Cosmetic Cotton Balls

This research aimed at preparing silver nanoparticles using the Novel chemical method, obtained as a black precipitate silver NPs. The sample was examined by using digital spectrometer device to find a degree of absorbency and its wavelength and particle by mathematical equation. Microbiology tests were carried out to determine the effectiveness of the sample in killing bacteria using the dilution method. After dissolving Silver NP`S in 5% acetic acid concentration, and covering the cotton balls with a solution of silver NPs to test the effectiveness of the sample using Two different concentrations of (0.5ml/g), and (0.25ml/g) and using two types of bacteria which causes skin blisters staphylococcus and streptococcus it is found that more concentration of the silver NPs solution has increased of killing both types of bacteria by staphylococcus (100%) and streptococcus (75%).
