A novel di-functional fluorescent probe for ONOO and Zn imaging in cells.

Peroxynitrite (ONOO) is one of the most significant reactive oxygen species (ROS) in living cells. Zn in living cells plays an essential part in different physiological processes. The abnormal concentration of ONOO and Zn in living cells are related to many kinds of diseases, such as anemia, epilepsy, diarrhea, Alzheimer's disease, and so on.
