Gold Nanoparticles in India – Aritech Nanomaterials India
Gold nanoparticles are chemically stable, biocompatible and easy to functionalise with thiols, antibodies and DNA. Their size-dependent colour, caused by surface plasmon resonance, is the basis of lateral-flow tests, colorimetric sensors and SERS. Aritech supplies gold nanopowders and colloidal gold from Nanochemazone® Canada to Indian diagnostics companies and research labs.

Gold Nanoparticles – Frequently Asked Questions
Why does colloidal gold look red?
Gold nanoparticles around 20 nm absorb green light through surface plasmon resonance, so the dispersion appears red. Larger particles shift the colour towards purple and blue.
Can gold nanoparticles be supplied in a specific size?
Yes. Colloidal gold is available in defined sizes; state the diameter and concentration you need on your enquiry.
How can I buy gold nanoparticles in India?
Click Get Quotation on the product page or email sales@chemazone.in with the product, quantity and delivery city. Aritech will send an INR quotation with GST and, once confirmed, arrange delivery.
