Quinoline-Based Fluorescence Sensors

The human body is full of various ions, which play an important role in the normal physiological activities. For example, Zinc ion (Zn2+) plays a vital role in protein organism and in many biochemical processes, such as inducing apotosis, enzyme regulation, and gene expression. Also, Ferrous ion (Fe2+) is vital in the oxygen transporting. But there are some ions harmful to human body. When exposed to mercury, even at a very low concentration, they lead to kidney and neurological diseases. What’s more, Cadmium (Cd2+) could damage our tissues, resulting in renal dysfunction or even cancers. So far, we have known more about these ions’ properties in metabolism, but little is known on mechanism.
