NanoXact is our original product brand and has our widest selection of materials and surface types. All NanoXact particles have high purity, are unagglomerated, and highly characterized.
Why Choose NanoXact?
Narrow size distribution & aggregation-free
Discrete sizes with coefficients of variation < 15% for most sizes. As with all nanoComposix products, BioPure nanoparticles have narrow size distributions and are aggregation-free so they maintain their unique nanomaterial properties.
Wide selection of surfaces & material types
Each surface imparts unique functional benefits, allowing you to select the surface that works best for your needs. For example, a bare citrate surface is easily displaced by other molecules, PVP offers stability in many polar solvents, and PEG offers good stability in high salt concentrations and biological buffers. For gold and silver nanoparticles, choose from surface options such as Bare (Citrate), PVP or PEG polymers, Tannic Acid, Carboxyl (Lipoic Acid), and Cationic/Amine (BPEI). Platinum is available with a Bare (Citrate) surface and magnetite is offered stabilized with PVP.
Know exactly what you’re getting. We perform extensive characterization on every batch of material we make and provide you with a batch-specific Certificate of Analysis that contains all of the characterization recommended for publication in scientific journals.
Dried Formulations Available
By carefully controlling the drying process, our dried powder formulations can be resuspended in a wide variety of solvents without aggregation. This is much simpler than transferring suspended particles to a different solvent using multiple centrifuge/wash cycles or filtration steps.
Why Purchase From nanoComposix?
We stand behind everything we make 100%. If for any reason you are dissatisfied with a material you've received, we will do everything in our power to make it right. See our Guarantee Policy for more information.
Surface chemistry and suspension buffer details are provided for each material, and no proprietary coatings or mystery chemicals are used.
