A highly selective and sensitive turn-on fluorescent probe for the detection of Al3+ and its bioimaging.

A novel fluorescent sensor, 1-((2-hydroxynaphthalen-1-yl)methylene)urea (ocn) has been designed and applied as a highly selective and sensitive fluorescent probe for recognition of Al3+ in Tris-HCl (pH = 7.20) solution. The probe ocn exhibits an excellent selectivity to Al3+ over other examined metal ions, anions and amino acids with a prominent… CONTINUE READING
