Form: light blue solution

Particle diameter: 40, 50, 60, 80, 100nm (can be customized according to needs)

Hollow, porous

Application: The surface of the gold nanocage is negatively charged and the surface charge can be modulated as needed.

The particles are hollow, porous, with high loading, safe, environmentally friendly and non-polluting. The surface-adsorbed sodium citrate layer is easy to further functionally modify.

Dispersion and stability.

It can be applied to photothermal therapy, biological immunoassay, chemical or biological sensing, dark field optical imaging, surface Raman scattering enhancement, drug or gene carrier, and the like.

other information

Compared with the solid gold nanoparticles, the plasmon resonance is only realized on the outer surface. The gold nanocage can achieve plasmon resonance absorption on both the outer surface and the inner surface due to its hollow nature, so it can be used as an excellent performance. The photothermal conversion agent causes tumor apoptosis by heating up by overheating. In addition, the porous structure on the surface of the gold nanocage greatly increases its "hot spots" as surface-enhanced Raman scattering and the substrate, and the electromagnetic field enhancement caused by the plasmon resonance of the inner and outer surfaces is superimposed, making it Surface-enhanced Raman scattering substrates with broad application prospects are expected to achieve single-molecule detection based on surface-enhanced Raman scattering of liquid phases.

Storage method: sealed, stored in a refrigerator at 4 ° C in the dark
