Quenching effect of nickel ions on fluorescent gold nanoparticles
Herein, we reported the quenching effect of Ni 2+ on bovine serum albumin protected fluorescent gold nanoparticles (BSA-GNPs). The quenching mechanism was discussed and a static quenching mechanism was proposed. The number of binding sites ( n), apparent stability constants ( K) and corresponding th...

| description | Herein, we reported the quenching effect of Ni
2+ on bovine serum albumin protected fluorescent gold nanoparticles (BSA-GNPs). The quenching mechanism was discussed and a static quenching mechanism was proposed. The number of binding sites (
n), apparent stability constants (
K) and corresponding thermodynamic parameters of BSA-GNPs-Ni
2+ complex were measured at different temperatures. Under optimum conditions, the fluorescence intensity of BSA-GNPs is linearly proportional to nickel concentration from 6.0
