Measuring the smallest of metal particles

April 28, 2014

CEE Professor Philip Larese-Casanova is exploring just how safe - or toxic - metallic components of our consumer products are after their disposal. The latest generation of electronic products contains metallic nanoparticles that can degrade and release toxic heavy metals into waterways.  Prof. Larese-Casanova and his students are developing new ways to detect and quantify these metal nanoparticles that occur in sizes less than 1000 times smaller than the width of a human hair. The methods will help us understand how these mixed metal nanoparticles will behave in water systems when released into the environment. Prof. Philip Larese-Casanova was awarded an NSF CAREER Award from the National Science Foundation for this work entitled "Quantum Dot Degradation in Aquatic Environments".
