Descrição geral

Gold nanoparticles have unique properties like biocompatibility, non-cytotoxicity, good optical and electronic properties. They are widely in targeted drug delivery, bioassays and polymer-based sensors. Gold nanorods exhibits a transverse plasmon resonance in the wavelength range of around 520 nm and longitudinal plasmon resonance in the wavelength range of greater than 600 nm which makes it very attractive for optical imaging in tissue since light in this wavelength range can penetrate deep into the tissue due to low absorption and scattering.

Aplicação

Used in cancer nano-therapy.

Características e benefícios

Strong light absorption, localized surface plasmon resonance, quantum effect, biocompatibility, low toxicity, consistency, easy synthesis, ability to be readily functionalized with targeting ligands.
