Application of a mercapto-terminated binuclear Cu(II) complex modified Au electrode to improve the sensitivity and selectivity for dopamine detection

A label-free aptasensor based on polyethyleneimine wrapped carbon nanotubes in situ formed gold nanoparticles as signal probe for highly sensitive detection of dopamine

“…Detection limit and linear calibration range of the proposed modified electrode were compared with those previously reported and the results are summarized in Table 1. As can be seen, the analytical parameters are comparable or better than the results reported for DA determination at the surface of other modified electrodes [33][34][35][36][37][38][39][40][41][42][43].…”

A unique turn-off fluorescent strategy for sensing dopamine based on formed polydopamine (pDA) using graphene quantum dots (GQDs) as fluorescent probe

“…Facile and accurate analysis of DA could greatly benefit the field of physiological function and clinical diagnosis of special neurological diseases. In the past few years, various strategies have been developed for DA detection, including electrochemical methods [15][16][17], enzymatic methods [18], photo-electrochemical sensor [19], and high performance liquid chromatography [20]. However, inherent shortcomings make these methods a bit difficult to satisfy the increasing requirements for simple, reliable, and cost-efficient methods.…”

Synthesizing a nano-composite of BSA-capped Au nanoclusters/graphitic carbon nitride nanosheets as a new fluorescent probe for dopamine detection

“…Moreover, a comparison of the proposed sensor with some other sensors for the detection of DA was also listed in Table 1. It was observed that the g-C 3 N 4 NSs-AuNCs as a fluorescent probe gave better or similar linear range and detection limit for detection of DA, as compared with some very recently reported methods, such as DPV [44,45], ECL [46,47], and fluorescence sensors [40,41].…”
