Tóm tắt

Nano silver has been studied and applied in many fields but is mainly known in medicine for its strong
antibacterial properties. The framework of this paper presents silver nanosolution prepared by
electrochemical method without using chemicals with high content of 108.5mg/L, without residual toxic
metal, average particle size below 40nm , the stability of the solution is expressed through a zeta potential
of -43.5mV. The bactericidal effect (Staphylococcus aureus; Pseudomonas.aeruginosa; Shigella flexneri)
of the nano solution was evaluated by direct contact with bacteria at concentrations of 80 times dilution
after 3 minutes, reaching over 84%.
