Product Overview<\/b><\/strong><\/h3>\n

PEI-modified silver nanoparticles are silver nanoparticles modified with polyethyleneimine (PEI), imparting a positive charge to their surface. This modification enhances both the biocompatibility and functionality of the nanoparticles. It grants the silver nanoparticles a range of unique properties, making them suitable for applications in drug delivery, gene transfer, and the development of antibacterial materials.<\/p>\n

Key Features<\/b><\/strong><\/h3>\n
    \n
  • Hydrophilicity<\/strong>: The PEI modification gives the silver nanoparticles excellent hydrophilicity, improving their dispersion in water and enhancing their application in biomedical fields.<\/li>\n
  • Functionalized Surface<\/strong>: The cationic nature of PEI boosts the particles’ ability to interact with cells, facilitating the delivery of drugs and genes.<\/li>\n
  • Customizability<\/strong>: The surface characteristics of the particles can be adjusted according to specific needs, optimizing their use in drug delivery systems.<\/li>\n
  • Antibacterial Properties<\/strong>: PEI modification enhances the antibacterial efficacy of the silver nanoparticles, providing strong antimicrobial activity.<\/li>\n
