Fluorophore Labeled Gold Nanoparticles

This technology utilizes the complete line of Accurate™ Spherical Gold Nanoparticles, Nanorods, Microgold™, and Gold Nanowires and allows the customer to choose the fluorophore and in vitro conjugation including amine, biotin, carboxyl, methyl, maleimide, neutravidin, streptavidin, and secondary antibody conjugations. These particles may also be conjugated to customer defined antibodies, peptides, oligos, and more. These conjugated particles can be used in brightfield, darkfield, fluorescence, and other imaging modes; and ELISA, lateral flow, and other assays. Although some fluorophores may be plasmonically enhanced by the correct choice of shape and sized gold nanoparticle, the designs allow for as many fluorophores as possible to be conjugated to each, and that there be no quenching of the fluorescence. Every batch is completely characterized including size, monodispersity, and concentration. A Certificate of Analysis (COA) is provided for every order exhibiting TEM and UV-VIS images and data, as well as DLS data.

"Nanopartz is sublime for their broad range of high quality products, which are, as they truthfully describe on their website of excellent quality. The fluorescent gold nanoparticles I'm using in my research are perfect: high density, stable and high fluorescent efficiency, so they're making my nanoparticle microscopy study so much easier. Moreover, their technical support is the best I have ever encountered in a company, very patient and extremely helpful and friendly. Thank you! "

Fluorophore labeled gold nanoparticle

Representative Construct for Fluorescently Labeled Gold Nanoparticles

SDS

How much thickness does your proprietary capping agent add?

It is less than the variablility of the size of the nanoparticles themselves, so it is unmeasurable.

Why do you sell your rods as OD-mLs and what does this mean?

This is because unlike spherical gold nanoparticles, the conversion from OD to mg is not linear with nanorod diameter. Consequently, for the same OD, the weight of the nanorods increases with diameter. 50 OD-mLs means that if you resuspend the material in 1mL of solvent, you will have an absorption of OD50 through a 1mL optical path.

Can I resuspend in water?

Yes

Should I store in the refrigerator?

Yes.

What is the total number of fluorophores on the gold nanoparticles?

Because of the many competing factors regarding fluorescence, ie instrument setup, bleaching, scattering, absorption, and quenching, it is impossible and not feasible to provide an exact number. The customer should measure the fluorescence from a known sample of nanorods given by UV VIS and calculate the fluorescence signal/nanorod in their application (ie salt, pH, and other controlling properties) instead, treating it like a composite product.

"We have looked at many different gold nanoparticles samples from Nanopartz including spheres, rods, and microrods using single particle spectroscopy techniques and are extremely happy with the quality of the samples and the service provided by Nanopartz."

"Nanopartz is sublime for their broad range of high quality products, which are, as they truthfully describe on their website of excellent quality. The fluorescent spherical gold nanoparticles I'm using in my research are perfect: high density, stable and high fluorescent efficiency, so they're making my nanoparticle microscopy study so much easier. Moreover, their technical support is the best I have ever encountered in a company, very patient and extremely helpful and friendly. Thank you! "
