Photobiomodulation (PBM) employs tissue-penetrating light to interact with intracellular chromophores, influencing cellular and tissue outcomes. Silver nanoparticles (AgNPs) enhance tissue regeneration through localized surface plasmon resonance under near-infrared (NIR) light, which stimulates osteoblast activity and provides antibacterial benefits. Designed to attain biocompatibility and interactions with blood proteins, AgNPs are ideal for photothermal therapy, enabling precise, non-invasive treatments to eradicate pathogens while supporting tissue healing and bone regeneration. This synergy of PBM and NIR-stimulated AgNPs represents a promising approach for advanced medical therapies, particularly in bone regeneration and infection control.
