Nanopartz™ Gold Nanowires

Nanopartz™ has developed the industry standard in Gold Nanowires. These nanowires are 75nm in diameter, and range from 1 µm to 10 microns in length.  In the bare form, these nanowires are immersed in DI water with excess CTAB capping agent to minimize aggregation.

A14 Gold Nanowires MSDS

FAQz

I want to use these nanowires in my sensor application - how do I go about doing that?

You are going to want to conjugate this nanowires to a ligand. We highly recommend our conjugating services for this.

What is the SPR for this product?

There is no Surface Plasmon Resonance for this particle as the diameter and length are too large, so these are not recommended for dark field microscopy. However, they are large enough to reflect light and are very advantageous for bright field microscopy.

I want to use this product in polymers for transparent electrodes. Can I use them as is?

Yes.
