GOLD NANOPARTICLE FOR SENSING (I)
As it is well-known the optical properties of gold nanomaterials are highly size and shape dependant. Particularly, in the case of spherical gold nanoparticles, they absorb light in the UV-Vis range (sensitive range for human eye) starting from 515 nm to longer wavelength (red shift) as the size of the gold nanoparticles increases. Moreover, larger […]
