nanoComposix is a world leading manufacturer of precisely engineered and highly characterized nanoparticles. Our mission is to help our customers bring nanotechnology enabled products to market. Our multi-disciplinary technical teams provide rapid prototyping, characterization, integration, and scale-up solutions to accelerate R&D and commercialization for a wide variety of application areas including biodiagnostics, topical therapeutics, nanomedicine, antimicrobial coatings, and color engineering.

We are a 12 year old company that has provided monodisperse and unagglomerated metal and metal-oxide nanomaterials to thousands of customers.  Hundreds of different variants of material, size, shape, and surface are available as stock products and we have produced over 2000 custom core/shell, biofunctionalized, fluorescent, and magnetic nanocomposites to meet client specifications.  NanoComposix produced the NIST nanosilver reference material and our particles have been utilized in over 400 peer-reviewed publications. All of our materials are supplied with certificates of analysis that include electron microscopy, hydrodynamic diameter, and optical data for each batch to guarantee products meets specifications. Contract manufacturing is performed on scales that range from small beakers to thousands of liters. Nanomaterials for medical devices and clinical trials are produced in our ISO13485 and cGMP compliant cleanroom facility. By leveraging our unique library of nanomaterials, we aim to help our customers rapidly bring nano-enabled products from concept to commercialization.

The motivation for starting nanoComposix was the frustration I had experienced as a scientist when trying to acquire high quality nanomaterials. Every time I ordered a product from a nanomaterial or chemical company I would spend many hours performing characterization only to realize that the shape, size distribution, agglomeration state or chemical purity was not what I was expecting. I would be forced to discard the material and try another vendor. This was a time consuming and completely unnecessary impediment to the development of technologies and products that leverage the new and exciting properties of nanomaterials. At nanoComposix, we provide extensive characterization data with each product that we sell. Additionally, our diverse team of scientists can provide solutions to the integration problems that are the main challenge for leveraging novel nanoscale properties into commercial products. It is my hope that with improved access to highly characterized nanomaterials, researchers will be able to accelerate the pace of nanomaterials research and products that harness the potential of nanotechnology. -Steve Oldenburg, President, nanoComposix


Dr. Steven Oldenburg ·
Founder and CEO ·
858-565-4227 x111
Ph.D. in Applied Physics, Rice University

Steve has over 20 years of nanotechnology experience beginning with his graduate work at Rice University where he discovered a method of fabricating gold nanoshells, a nanoscale composite material that consists of a spherical silica core surrounded by an ultra-thin shell of gold.  This discovery led to the formation of Nanospectra Biosciences where the gold nanoshells are in clinical trials as a cancer therapy. After Rice, he joined Seashell Technology where he was responsible for identifying and developing commercial applications of nanotechnology, raising capital, and managing the scientific research team. In 2004 he founded nanoComposix to accelerate the commercialization of products based on precisely engineered and highly characterized nanoparticles.  He is also a co-founder of Sienna Labs, a company that is developing therapies based on novel medical pigments. Steve has 6 issued patents and has over 30 nanotechnology publications that have received >5000 citations.
