Abstract

The noble metal nanoparticles, for example gold and silver nanoparticles, absorb strongly in the visible and near-infrared region when the frequency of an electromagnetic field becomes resonant with the surface plasmon coherent electron oscillation within the nanoparticles. Nowadays nanoparticles are widely used in photodynamic therapy (PDT) for treating cancer in vivo. The experiments regarding nanoparticle synthesis were conducted in plant extracts (Azadirachta indica, Anethum graveolens and Salvia officinalis)..
