A novel fluorescent probe (XL-1) exhibited over 50-fold enhanced fluorescence in the presence of Hg2+ and no interference could be produced by other metal ions, anions and amino acids.
The emission intensity of red emissive GSH-AgNCs is notably enhanced after the addition of dopamine. The increasing emission intensity is attributed to the hydrogen bonding interaction between the carboxyl groups of GSH-AgNCs and amino groups of dopamine.
A novel biotin fluorescent probe based on oligonucleotide-stabilized silver nanoclusters (DNA-AgNCs) was synthesized by employing a biotinylated cytosine-rich sequence as a synthesized template.
