The core of Silica Gold Nanoparticles has unique optical properties. The chemically inert silica shell layer does not affect the properties of the original core, while reduces the van der Waals force between the Gold nanoparticle cores.
Silica Gold Nanoparticles have a wide range of applications, such as good stability, uniform shape, good light permeability, biological affinity, easy to functionalize biological proteins, oligonucleotides, Enhanced Raman spectroscopy, medical imaging, drug delivery, etc. In addition to the excellent optical properties and biocompatibility of conventional.
Abvigen Inc¡¯s Silica Gold Nanoparticles contain sulfhydryl group inside and outside of the silicon layer, which can be directly reacted with fluorescent molecule, oligonucleotide without any additional steps. The Diameter is adjustable from 1.8 nm to 1500 nm, and the thickness of the silicon layer can be adjusted between 1.5 nm and 65 nm as required.
Diameter: 20 nm, 40 nm, 60 nm ; Silicon Shell: 50 nm
On the basis of determining the size of the gold core , as the thickness of the silicon layer increases, the maximum ultraviolet-visible absorption spectrum of the Silica Gold Nanoparticles will red-shift due to the change of the dielectric constant. Please refer to the datasheet for specific parameters.
Diameter: 40 nm; Silicon Shell: 1.5nm, 2.5nm, 5nm, 25nm, 50nm, 65 nm
