How do you size your gold nanoparticles? Does the size include the capping agent?

We use three methods to specify our gold nanoparticles; TEM, UV VIS, and DLS. Each has its own advantages and disadvantages, and we use a weighted system to take advantage of each methods strengths. In the end, we place the strongest weight to the TEM method, particularly since we use samples sizes greater than 50 particles for each lot.

Do you really provide a TEM for my specific lot?

Yes, and not just for 5-10 particles, rather 50-100 are standard.

Filtration systems by themselves are not a novel product, nor is using other items (charcoal, etc) to enhance the effectiveness of said filter. What is a novel creation is the ability to suspend nanomaterials to a glass fiber filter to allow further functionalization and capabilities, as well as utilizing the immense surface area created by nanomaterials. In the following, Nanopartz has discovered many different options to utilize our proprietary enhanced filtration systems for a multitude of uses, and can even tailor the filters specifically for your application. Already a world leader in gold nanoparticle production, manufacturing, and research, Nanopartz is now using bi-metallic nanomaterials and functionalization to specifically target any application that uses a filtration process. Uses Filter systems are of great use to filter out unwanted antibodies for certain tests that may affect the outcome of a test or even the health of a test subject. Removal of antibodies in an ABO-incompatible transplantation can prevent hyperacute organ rejection¹ using a filter with specific antibodies. Nanopartz Enhanced Filtration systems have the ability to exactly match the amount of assumed antibodies and utilize our antigen functionalized product lines to remove unwanted antibodies with precision and covalent bonding. This is possible with our proprietary loading techniques to allow our GNP’s to be suspended on glass filters of any pore size and still be functionalized after the fact.

 

Catalysis and its uses are innumerable because of new findings on the ability of nanomaterials to be a reactive catalyst towards any number of reactions. Nanopartz bi-metallic alloys can play a support role in catalytic activities. It is found that GNP’s provide a synergistic enhancement effect that involves the suppression of adsorbed poisonous species and a change in electronic band structure to modify the strength of surface adsorption².(Synergistic activity of gold-platinum alloy nanoparticle catalysis). Bi-metallic combos enhance the properties of one and another and noble metals have been testified to do a good job in prohibiting the electron-hole recombination due to the fact that noble metals would facilitate the separation of photogenerated electron-hole pairs and promote interfacial charge transfer³ (electrospinning fabricating Au/TiO2 network ike nanofibers as visible light activated photocatalyst). There are many applications that have to use different particle shapes to allow for catalysis to happen, as found in the most recent cited paper, but Nanopartz Alloys are stable in any solution with only a basic capping agent that doesn't affect its catalytic abilities. Nanopartz offers spherical alloys, as well as spherical nanoparticles, and rod shaped particles that can be used for such applications. NEFS can be used for many different catalysis applications as seen in “Synergistic Activity of Au-Pt alloy nanoparticle catalysis,” where the researchers used Au-Pt alloys for methanol oxidation. They found that Au didn’t have any negative effect on the performance of the Pt, but was actually enhanced when compared to only a Pt based particle filter.
