Silver nanoparticles (AgNPs) are tiny particles of silver - typically ranging from 1 to 100 nanometers in size. They exhibit unique physical, chemical, and biological properties distinct from bulk silver. They are the driving force behind Poseidon.
At the nanoscale, silver behaves differently. Its large surface-area-to-volume ratio enhances its chemical reactivity, giving it antimicrobial, anti-inflammatory, and antioxidant properties that have made it one of the most studied nanomaterials in biomedical research.
The primary mechanism behind AgNPs' effectiveness is their ability to disrupt bacterial cell membranes, generate reactive oxygen species (ROS), and interfere with microbial DNA replication.
This multi-targeted antimicrobial action makes it difficult for bacteria to develop resistance, unlike traditional antibiotics.
Additionally, AgNPs can modulate the local inflammatory response and help prevent biofilm formation - both of which are crucial in wound management, where infection control is one of the biggest clinical challenges.
Bacterial contamination can delay healing, prolong inflammation, and even lead to chronic, non-healing wounds.
Silver nanoparticles offer a powerful tool to address this challenge.
They can be incorporated into wound dressings, hydrogels, or scaffolds to provide localized antimicrobial protection without the need for systemic antibiotics.
Beyond their antibacterial action, AgNPs have also been shown to:
✅ Reduce inflammation in the wound bed
✅ Minimize oxidative stress
✅ Support fibroblast activity and tissue regeneration at low, controlled doses
At Asclepii, we recognize the promise of nanomaterials like AgNPs in wound care, and harness their potential for your healing.
