Nanopartz™in vivo Gold Nanoparticles
Nanopartz™ gold nanoparticles for in vivo application include both the Ntracker™ and Ntherapy™ family of nanorods, along with customer defined oligo and antibody conjugated nanrods for in vivo applications. The Ntracker™ non reactive methyl terminated nanorods are coated in a proprietary dense layer of hydrophilic polymers that shield the gold surface and give the particles ultra-long circulation times. Ntherapy™ nanorods come with similar hydrophilic polymers, but with terminal amine and carboxyl active groups, along with a number of custom popular in vivo targeting ligands. Ntherapy™ also provides an opportunity for the customer to define their own targeting ligands utilizing Nanopartz™ nanorod and polymer technologies. In this family, Nanopartz™ has the ability to covalently conjugate to specific antibody locations, thereby for example, leaving necessary primary amines exposed for optimum activity. The combination of the highly monodisperse Nanopartz™ gold nanorods with the proprietary Nanopartz™ polymers increase circulation times 50% longer than other commercial polymers thereby significantly improving targeting. As opposed to other commercially available nanoparticles such as quantum dots, Nanopartz™ in vivo line of nanorods are completely non-toxic. Whereas Ntracker™ takes advantage of the Enhanced Permeability and Retention effect (EPR) for passive in vivo targeting, Ntherapy™ utilizes popular ligands for active targeting. This product line comes in a diameter of 10nm with SPRs matching all of the popular Near IR CW laser wavelengths; 780, 808, 850, 980, and 1064nm. Ntherapy™ offers options for oligo and customer detailed conjugations. Every batch is radiation sterilized in PBS, and comes with instructions for in vivomouse iv injection. A Certificate of Analysis (COA) is provided for every order exhibiting TEM and UV-VIS images and data, as well as DLS data. Every product is in stock (99%) and is shipped next day for many ligands. This product comes in two concentrations, regular 1.75mg/mL, and highly concentrated 10mg/mL.
Nanopartz™ In Vivo Plasmonic Fluorophores™ are fluorophore decorated gold nanorods manufactured using multiple patent pending and proprietary methods that result in fluorophores that exhibit much higher intensities than conventional fluorophores, no photobleaching even under the highest laser intensities, with long circulation times in vivo. Peak fluorescence range from 780 to 1064nm utilizing the same nanorods and in vivo polymer used in our Ntracker and Ntherapy products.
