Overview

Description

Gold nanoparticles dispersion is to disperse gold nanoparticles into a solvent to form a neutral solution with stable and uniform color. The color of the solution is not golden yellow but red. If other substances are added to form a condensed state, the solution turns blue. The solution has the same antibacterial properties as nano silver, and also has better safety for human consumption and contact. Gold nanoparticles have been widely used due to their unique physical and optical properties.

Features

·Evenly dispersed, small particles
·Good compatibility, easy to disperse, easy to add a variety of systems
·Good system stability, reliable performance, safety and environmental protection
·High specific surface area, high loading, easy surface functionalization

Application

·Electronics: Gold nanoparticles are used as conductors in everything from printing inks to electronic chips.
·Photodynamic therapy: Gold nanoparticles (including nanoshells and nanorods) in the near-infrared absorption band generate heat when excited by light at wavelengths of 700 to 800 nm. This feature enables the nanoparticles to destroy targeted tumors.
·Therapeutic agent delivery: Therapeutic agents can be coated on the surface of gold nanoparticles.
·Sensors: Gold nanoparticles are used in various sensors.
·Diagnosis: Detection of Biomarkers
·Probes, catalysis, fuel cells
