title: Carbon-dot-based dual-emission nanohybrid produces a ratiometric fluorescent sensor for in vivo imaging of cellular copper ions.
abstract: A sensitive biosensor: A strategy for the intracellular imaging of Cu(2+)  ions has been developed by integrating a recognition molecule, N-(2-aminoethyl)-N,N,N'tris(pyridin-2-ylmethyl)ethane-1,2-diamine (AE-TPEA), into a hybrid system composed of carbon and CdSe/ZnS quantum dots.
