Method of Nanoparticle Analysis

The Problem:
Nanoparticles are being utilized in multiple industries. With more use of nanoparticles in the commercial and academic sectors there is a need to ensure that each batch of nanoparticles produced is homogenous in size and physical properties. Current nanoparticle analysis technologies can’t measure both electrochemical and optical properties of nanoparticle product at the same time.

The Solution:
Researchers at the University of Alabama have developed an innovative arrangement of readily available laboratory equipment combined with a novel electrochemical cell and a powerful MATLAB software package that allows for rapid and precise in situ nanoparticle characterization. The invention measures a variety of spatial and temporal information through a combination of dark field scattering and electrochemilumenescence optical signals, allowing for the analysis of thousands of nanoparticles simultaneously.


  • Rapid on-site determination of nanoparticle size, size distribution, and the redox potentials.
  • More sensitive than currently available techniques.
  • Able to analyze a single molecule or nanoparticle, which is not possible with current technologies.
  • Compact and miniaturized.
  • Can be customized based on different types of nanoparticles and chemilumenescence.

The University of Alabama Research Office of Innovation and Commercialization (OIC) is a non-profit corpo­ration that is responsible for commercializing University of Alabama technologies and for supporting University research. At OIC, we seek parties that are interested in learning more about our technologies and commercialization opportunities, and we welcome any inquiries you may have.
