NanoBright® Gold Nanoparticles:
NanoBright® gold nanoparticles from Nanocs have narrow size distribution yet with multiple size selection from 2 nm to 250 nm. These gold nanoparticles have spherical shape, completely soluble in water, have been used widely for the development of diagnostic probes, therapeutic agents and drug delivery vehicles. The optical and electronic properties of gold nanoparticles are tunable by changing the size, shape, surface chemistry and aggregate state. These gold nanoparticles can be further modified with different surface coatings and functional groups to render them with unique chemical and biological reactivity. Nanocs surface modified gold particles provide more choices for in-vitro or in-vivo applications of those nanoparticles. Customer conjugation and modification is available upon request.
