Abstract An “Off–On” approach for highly sensitive and selective detection of mercury ions
(Hg 2+) and l-cysteine (l-Cys) was demonstrated with the use of water-soluble carbon dots …

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 …

Carbon dots (C-dots) are superior in the aspects of excellent water solubility, good
biocompatibility, environmentally friendliness and non-blinking fluorescence. In this work …

The copper doped fluorescent carbon dots (Cu-CDs) with excellent biocompatibility were
prepared from l-tryptophan and copper chloride as precursors through a facilely …

We herein report a facile, one-step pyrolysis synthesis of photoluminescent carbon dots
(CDs) using citric acid as the carbon source and lysine as the surface passivation reagent …

Carbon dots (CDs) have been widely used in recent years because of their excellent water
solubility and abundant surface functional groups. However, compared with quantum dots or …

In this work, we explored the use of Acacia concinna seeds (shikakai) as a green precursor
for the fabrication of ultra-small fluorescent carbon dots (CDs). The synthesized ultra-small …

Water contamination by copper ions (Cu 2+) and sulfide anions (S 2-) has been a
longstanding human health hazard. The limitations of current detection strategies have …

Highly fluorescent carbon dots (CDs) are prepared by a one-step microwave heating
method using citric acid, L-cysteine and dextrin as the precursors. The average size of the …

Due to the advantages of in situ, real-time, and non-destructive detection of target
molecules, fluorescent probes have become an indispensable tool in the fields of disease …
