Note: according to user requirements of nano particle can provide different size products.

What our customers say?“The gold and conjugation processes at HOWU are unrivaled – we found that HONGWU was the best that we could work with.”

HONGWU’s unique manufacturing technique allows for the production of large batches of gold nanoparticles to a high level of reproducibility of size, dispersion and shape.

Application direction

Gold nanoparticles are a suspension consisting of nano sized gold suspended within a solvent, most often water. They have unique optical, electronic, and thermal properties and are used in a wide range of applications including diagnostics (lateral flow assays), microscopy and electronics.

1. Catalytic-gold nanoparticles are used as catalysts in many chemical reactions.

2. Sensors - Gold nanoparticles are used in a variety of sensors. For example, a gold nanoparticle-based colorimetric sensor can tell if food can be eaten.

3. Electronics - From printing inks to electronic chips, gold nanoparticles can be used as their conductors.

4. biological detection---Colloidal gold is widely used in biological detection, including influenza detection, drug detection, novel coronavirus antigen detection.

For nanoparticles material application, to disperse them well is usually a hard part for unexperienced users, offer nano Au colloidal / dispersion / liquid make it easier and more convenient for direct use.
