Highly sensitive and selective fluorescent detection of cerebral lead(II) based on graphene quantum dot conjugates

Chem Commun (Camb). 2013 Nov 21;49(90):10599-601. doi: 10.1039/c3cc46059b.

Abstract

A novel probe based on graphene quantum dot conjugates was developed for fluorescent detection of Pb(2+) (LOD: 9 pM) and furthermore for monitoring Pb(2+) in the striatum of rat, combined with microdialysis sampling in vivo.
