BioPure nanoparticles are unagglomerated and highly characterized nanoparticles that are tailored for use in biological assays.
Why Choose BioPure?
Extensively washed to remove residual reactants
Purified to remove 99.99% of residual reactants. Many commercial nanomaterials contain residual reactants and contaminants introduced during manufacture and handling. nanoComposix BioPure™ particles are extensively washed using proprietary filtration techniques, so you can be assured the nanoparticles you’re using are purified and free of contaminants.
Guaranteed sterile and endotoxin-free
All BioPure materials are handled in sterile environments and each batch is tested to guarantee endotoxin levels below 2.5 EU/mL for most sizes. Endotoxin is a common contaminant originating from bacteria that is abundant in the environment. Endotoxins elicit strong inflammatory and immune responses in animals, making it crucial to ensure your nanoparticles are endotoxin-free before using them in any medical or biological experiments.
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.
BioPure particles are available at 1 mg/mL to allow for easy dilution into your solvent or system. With concentrations 20–50 times higher than most standard nanoparticle products, BioPure particles allow you to administer smaller volumes or to easily dilute to the concentration that’s right for you.
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.
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.
