Based on the ability of lysine (Lys) to enhance the fluorescence intensity of
bovine serum albumin modified-carbon dots (CDs-BSA) to decrease surface defects
and quench fluorescence of the CDs-BSA-Lys system in the presence of Cu(2+) under
conditions of phosphate buffer (PBS, pH = 5.0) at 45 °C for 10 min, a sensitive
Lys enhancing CDs-BSA fluorescent probe was designed. The environment-friendly,
simple, rapid, selective and sensitive fluorescent probe has been utilized to
detect Cu(2+) in hair and tap water samples and it achieved consistent results
with those obtained by inductively coupled plasma mass spectroscopy (ICP-MS). The
mechanism of the proposed assay for the detection of Cu(2+) is discussed.
