Important Features 
  • High stability in suspension
  • Very small size​ between 5-25 nm
  • Four times stronger antimicrobial effect as compared to other commercial silver nanoparticles at the same mass concentration
  • AGNP+BPEI has positives charge surface,and many studies have proven  the surface charge plays an important role in bactericidal activity of AgNPs against both gram-positive and gram-negative bacteria. Among different AgNPs tested, the positively charged NPs were the most effective antimicrobial materials against all tested bacterial species.
  • Can be used in a wide range of applications
  • Narrow size distributions 
  •  AGNP+PVP is very stable and never aggregated
