Gold nanocolloids 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.

      Gold nanoparticles colloids can also be used to optimize the biodistribution of drugs to diseased organs, tissues or cells, in order to improve and target drug delivery.

      Customized production and service are available here, you can specify the particle size, the solvent, concentration, etc.

What our customers say?

      “The Gold nanocolloids and gold nanoparticles at HOWU are unrivaled – we found that HOWU was the best that we could work with.”

      HOWU’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.

      We pay special attention to the quality assurance of the products and services we deliver. We believe that this is the best way to make products work as effectively as possible.
