Detailed Technology Description

Researchers at the University of California, Santa Barbara have developed a method for the synthesis of highly dispersive inorganic nanoparticles with narrow size distribution. The limitations of prior methods (e.g. bulky reaction under constant Argon flow with a heating mantle operating at 240°C) are overcome by a novel heating process that features a high ramping rate, producing high crystallinity of the nanoparticles. This novel method of synthesis is fit for safe, large-scale, reproducible, and energy efficient production of colloidal nanoparticles. In addition, this method allows for the mass production of colloidal nanoparticles that can enhance the sensitivity and specificity of biological sensors.  The offered patent portfolio consists of 3 issued U.S. patents with broad method claims and claims to certain nanoparticles produced by the patent methods.

Background

Colloidal nanoparticles feature unique electronic, optical and magnetic properties that make them ideal tools for many applications in science, such as in biological sensing and tagging. The industry is, however, hampered by lack of a high-quantity synthetic methodology adaptable to high throughput automation for colloidal nanoparticles.  The featured technology overcomes many current problems with automation.
