What Nanopartz Inc. does

Nanopartz Inc. is a privately held specialty nanomaterials manufacturer founded in 2010 and headquartered in Loveland, Colorado. The company synthesizes gold nanoparticles — spherical particles from 1.8 nm to 1500 nm, gold nanorods with surface plasmon resonances from 550 nm to 2100 nm, and additional morphologies including nanocubes, nanostars, nanoplates, nanotriangles, nanowires, nanobipyramids, hollow nanoshells, and microgold — using a proprietary slow-reduction method described as yielding >99.9% monodispersity, ±2 nm size accuracy, and shelf life exceeding one year. Beyond gold, it offers gold-coated magnetic, carbon, cesium oxide, copper MOF, and platinum/palladium nanoparticles.

Beyond synthesis, Nanopartz operates a functionalized-product portfolio spanning PEG, antibody, peptide, oligonucleotide/DNA, click chemistry, NiNTA/HisTag, and zwitterionic surface chemistries, plus diagnostic SKUs (Ramanprobes SERS labels with zeptomolar sensitivity, lateral flow, zero-order SPR, SHINERS, plasmonic PCR) and in vivo products for imaging (NTracker), photothermal therapy (NTherapy), and biosensing (NSense). It also sells consumable kits including One Step Conjugation kits, antibody quality testkits, and sodium azide purification kits.

The business model combines transactional e-commerce sales of catalog SKUs (starting at $250–$580 per unit, with concentrated OD=100 and conjugated variants priced at premiums of $400–$2,840) with a tiered OEM Partner Development Program (Platinum, Silver, Gold) that supports custom synthesis, exclusivity rights, and 0–100% technology-ownership agreements. Customers include university research labs (Rice, Harvard-MIT, JILA, Lakehead, Harvey Mudd, IIT Genova), Fortune 500 corporates in life sciences/diagnostics, and OEM partners. Distribution is direct-to-customer via FedEx Overnight (domestic) and FedEx 2-Day International Priority with temperature-controlled packaging; 99% of products ship same day from stock.
