Photo at left: Selene Sepulveda Guzman, post-doctoral fellow in chemical engineering, also assists Dr. Yacaman with nanoparticle research. The colorful bottled materials appearing in the background are vials of ZnO nanoparticles under a UV lamp. These nanoparticles have potential application as biosensors.
