Natassja Lewinski, Ph.D., associate professor in the Department of Chemical and Life Science Engineering, recently gave a TEDx talk about the use of nanotechnology in the preservation of coral reefs.

“Nanotechnology is the understanding and control of matter at the nanoscale, at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications,” Lewinski says, citing the National Nanotechnology Initiative (NNI). 

Lewinski's research group investigates whether nanomedicines can mitigate coral heat stress by reducing reactive oxygen species. Initial findings suggest promise in using cerium oxide nanoparticles (CeNPs), or nanoceria, which are nanoparticles being studied for their antioxidant properties. However, Lewinski stresses the necessity of rigorous testing and responsible development to ensure the safety and effectiveness of nanotechnology in marine environments.

Lewinski’s research and teaching emphasizes the movement towards responsible progress in tackling global challenges like climate change.
