Fluorescence sensing by carbon nanoparticles

“…Nan and co-workers reported the use of a hybrid nanosensor for the detection of Fe 3+ based on a simple and fast spectrofluorimetric analysis. 130 They fabricated this sensor using ZnO/CdS nanoparticles modified with carbon nanoparticles. The sensing is based on the strong fluorescence quenching of the nanoparticles by the Fe 3+ ion due to the strong interaction between them and iron ions.…”

Synthesis of two nitrogen-doped carbon quantum dots to construct fluorescence probes for sensitive Hg2+ detection with dual signal output

“…Carbon quantum dots (CQDs) have attracted much attention from researchers owing to their unique luminescence properties, outstanding biocompatibility and great water solubility. [4][5][6] CQDs are regarded as potential nanomaterials for molecular sensing and biomedical applications, 7 and CQDsbased fluorescence probes have been successfully applied for the detection of metal ions, [8][9][10][11][12] amino acids, 13 nucleic acids [14][15][16] and glucose. 17 Many CQDs-based fluorescence probes have been proposed for the sensitive detection [18][19][20][21] of metal ions such as, Ag + , Hg 2+ , Cu 2+ , Cr 3+ and Mn 2+ , demonstrating the feasibility and practicality of these probes for metal ion detection in the environment and food.…”
