AuNPs are stable (inert) and non-toxic.
AuNPs can be used in a variety of applications in biomedical fields.
Surface plasmon resonance (SPR) is a crucial novel optical phenomenon possessed by plasmonic Gold nanoparticles (AuNPs), which are produced by electromagnetic radiations whose electrical constituents cause the excitation of free electrons (surface electrons) in metal.
The electronic oscillation of surface electrons results in a charge separation, which in turn produces dipole oscillation that works parallel to the direction of the electric field of the electromagnetic waves. The frequency (specific) at which the amplitude of the oscillation is maximum is called SPR frequency.
The band intensity of the SPR band is greatly affected by those factors, which also affect the surface’s electron charge density, such as surface morphology, composition, dielectric environment, metal type, and particle size. In the SPR phenomenon, the collective oscillation of electrons, due to interaction between light and surface electrons, has two modes: surface plasmon–polarization (SPP) and localized surface plasmon resonance (LSPR).
AuNPs are stable (inert) and non-toxic in a wide variety of environments with controllable optoelectrical properties. Owing to these benefits, AuNPs can be used in a variety of applications ranging from the environmental and energy sectors to biomedical fields.

Numerous free electrons exist inside the metal, which is a conductor. Since free electrons are not bound to metal atoms, they can easily respond to specific external stimuli. In particular, when a metal becomes nano-sized, a surface plasmon resonance characteristic appears due to the behavior of such free electrons and thus has unique optical properties. Surface plasmon resonance refers to a phenomenon in which free electrons on the metal surface collectively vibrate due to resonance with an electromagnetic field of specific light energy when light is incident between the surface of a metal nanoparticle, which is a conductor, and a dielectric such as air or water. Since the frequency of surface plasmon resonance varies depending on the size or shape of the metal nanoparticles, the dispersed solvent, etc., they can be adjusted and applied to applications using light of various wavelengths.
Gold nanoparticles (AuNPs) have been widely studied and applied in the field of tumor diagnosis and treatment because of their special fundamental properties.
Gold Cloud PAR is optimized for devices using various lights, laser, plasma, and IPL.
