Product name

Chinese name: Au Nanocage

English name: Au Nanocage

Nature

Form: light blue solution

parameter

Particle diameter: 40, 50, 60, 80, 100nm (can be customized as required)

Hollow particles, porous

Application

The surface of the gold nanocage is negatively charged, and the surface charge can be adjusted as required.

The particles are hollow, porous, with high loading, safe and environmentally friendly, and pollution-free. The sodium citrate layer adsorbed on the surface is easy to further functional modification.

Good dispersibility and stability.

It can be applied to photothermal therapy, biological immune detection, chemical or biological sensing, dark field optical imaging, surface Raman scattering enhancement, drugs or gene carriers, etc.

Other information

Compared with solid gold nanoparticles whose plasmon resonance is only achieved on the outer surface, gold nanocages can achieve plasmon resonance absorption on both the outer surface and the inner surface due to the hollow nature of the gold nanocage, so it can be used as a better performance The photothermal conversion agent causes tumor apoptosis through overheating. In addition, the porous structure on the surface of the gold nanocage greatly increases its “hot spots” as a surface-enhanced Raman scattering and substrate, and the electromagnetic field enhancement effect caused by the superimposed plasmon resonance on the inner and outer surfaces makes it a The surface-enhanced Raman scattering substrate with broad application prospects is expected to realize single-molecule detection based on surface-enhanced Raman scattering in the liquid phase.

Storage method: sealed, refrigerated and protected from light at 4℃
