Assessing Cytotoxic and Antibacterial Effects of High Dispersion-Stable Sub-5 nm Silver Particles
Summary: This research investigates sub-5 nm silver nanoparticles engineered for high colloidal stability. The particles exhibited potent antibacterial effects against common wound pathogens while showing manageable cytotoxicity in relevant cell models. The improved dispersion stability addresses previous limitations of silver nanoparticles (aggregation, inconsistent release, and higher toxicity). Authors suggest potential applications in wound dressings, topical antimicrobials, and infection-prevention coatings where sustained, controlled antibacterial activity is needed without compromising healing.
Key Highlights:
- Sub-5 nm AgNPs with superior dispersion stability
- Strong antibacterial activity with optimized cytotoxicity profile
- Addresses key barriers to clinical translation of silver nanomaterials in wound care
Keywords: silver nanoparticles wound, antibacterial wound dressing
