A silver plate was used as the cathode instead of silver salts to avoid unexpected ions from the salts. The cathode was made from a stainless steel plate. The chemical used as the electrolyte solution is TriSodium Citrate (TSC). Silver nanoparticles made by the above method are spherical, small-sized, its size distribution ranges from 3-12nm, stably dispersing in a non-toxic solution.Bactericidal capacity of silver nanoparticles are tested on 4 types of common bacteria and fungi. The results showed that silver nanoparticles with a concentration of 10 ppm have a good bactericidal capacity against the said bacteria. This result shows that silver nanoparticles made by heat-combined electrochemical method can be used in antibacterial applications.Keywords: Silvernanoparticle, electrolysis, TriSodium Citrate, antibacterial.}, issn = {2588-1124}, url = {https://js.vnu.edu.vn/MaP/article/view/108} }
