Dear Dr. Abdullahi Abbas Adam and Dr. Artur Braun ,

I have found several sellers on-line:

-Chemondis – Zinc Oxide Naniparticles Suspension

Available at: https://chemondis.com/marketplace/search/?query=1314-13-2&gclid=EAIaIQobChMI4Yztvaql6gIViKoYCh3RewDXEAAYAiAAEgLlZPD_BwE

-IOLOTEC’s Selection of Nanomaterials: Zinc oxide (ZnO), 90-210 nm, 99.9%

Available at: https://nanomaterials.iolitec.de/en/products/oxides/NO-0039-UP

-SSNano - Zinc Oxide Nanoparticles/ Nanopowder( ZnO, 99.8%, 10~30nm)

Available at: https://www.ssnano.com/i/u/10035073/h/Specification/Product_-_ZnO_Nanopowder_-_8410DL.pdf

-Particular Materials - Zinc Oxide (ZnO) nanoparticles

Available at: https://particularmaterials.com/index.php/products/zno-nanoparticles/

-Future Markets - The Global Market for Zinc Oxide Nanoparticles

Available at: https://www.futuremarketsinc.com/zinc-oxide-nanoparticles/

and there are several other sellers ....

It is not my specific sector but can you explain to me where the make-up is?

Do they sell nanopowers instead of nanoparticles, is it because of how they are supplied (e.g. suspension) or is it a problem of product reliability (e.g. impurities)?

Thank you very much and best regards, Pierluigi Traverso

you can easily purchase ZnO nanoparticles at great price from NANOSHEL.

Hi Abdullahi

You can buy them from Sigma Aldrich. Depending on your necessity, you can buy the ZnO powder or the dispersion(in ethanol or in water) with different particle sizes. You can look more about them in this link https://www.sigmaaldrich.com/catalog/product/aldrich/721077?lang=en®ion=US

Thanks

Dear Abdullahi Abbas Adam, STREM Chemicals also sells ZnO nanopowder for a good price (see attached).

Dear Abdullahi Abbas Adam you might as well consider preparing your ZnO nanoparticles yourself. It's rather easy and there are suitable references available as full texts on RG.

Hi Abdullahi,

You may make an inquiry at Alfa Chemistry, they offer kinds of good-quality zinc oxide nanoparticles.

Dear Abdullahi Abbas Adam in the meantime, did you manage to buy a sample of ZnO nanoparticles? If not, I think it might be a good idea to prepare them yourself. It's not really difficult.

You may buy ZnO nanoparticles in various size range at very affordable price budget
