Spherical Gold Nanoparticles

Gold nanoparticles are one of the most widely used classes of nanomaterials for chemical, bioanalytical, biomedical, optical and nanotechnological applications. While there are numerous methods known for the synthesis of gold nanoparticles, the ability to control the size, shape and monodispersity for gold nanoparticles is one of the important areas in which few standard protocols have been established to allow preparation of gold nanoparticles of desired sizes, shapes and monodispersity in a systematic way. Such ability is critical for many applications. We have developed a patent pending technique which can form any desired size in the range of 30-90 nm diameters.  The result is a gold nanoparticle that when compared with citrate capped nanoparticles, have better size and shape monodispersity, reduced batch to batch variation, and improved reactivity.

Gold Nanorods

The limitation on commercializing gold nanorods has always been monodispersity and scaling.  Up until now, nanorod production has been limited to volumes of less than 100 ml.  To overcome this limitation, we have exclusively licensed rights to patent pending nanorod manufacturing methods developed by Dr. Cathy Murphy at the Univ. of South Carolina and Dr. Eugene Zubarev at Rice University.  This technology combined with our in-house proprietary methods result in gram-scale synthesis of well-defined gold nanorods with a near-quantitative yield.  This means we can manufacture 5-10 liter batches of nanorods that are highly monodisperse in size, shape, and reactivity.  Further, the production methods allow for tuning of the nanorods to the desired absorbance peak.
