Nanoparticles, Nanotubes, and Quantum Dots
Our scientists have developed in-house capabilities in colloidal and aerosol science to synthesize, modify, and integrate customized nanoparticles and quantum dots using state-of-the-art techniques. These nanoscale materials are being used in diverse program areas, including
- Nanocomposites and polymer formulations
- Probes to measure filtration efficiencies
- Nanoscale materials characterization and instrument protocols
- Environmental and occupational fate and transport
- Optical properties and performance
For example, we are using quantum dots to increase the efficiency of solar cells, and we are developing large-area arrays of infrared photodetectors fabricated by inkjet printing. We are also combining quantum dots and nanofibers to create photoluminescent nanofibers that can be tailored for specific end-use applications such as white lighting. We have also developed a method for synthesizing radiolabeled carbon nanotubes and buckyballs. This type of radioactive tag enables researchers to study the fate and transport of nanoparticles in biological systems as well as in the environment.
