Carbon dots were synthesized by a simple and green strategy for selective and sensitive
Cu2+ ion detection using both down and upconversion fluorescence. These fluorescent …

An efficient strategy for selective fluorescent detection of Cu2+ was developed based on the
carbon quantum dots (CQDs) nanoconjugated with a specific organic molecule, amino …

A novel sensing system has been designed for the detection of cupric ions. It is based on the
quenched fluorescence signal of carbon dots (CDs), which were carbonized from poly …

A highly sensitive and selective fluorescent “on–off–on” strategy is established for the
synchronous detection of Cu2+ and glutathione in aqueous solution. Red carbon dots (R …

Abstract Copper ion (Cu 2+) and l-cysteine (l-Cys) detection is critically important since an
abnormal level of Cu 2+ or l-Cys is an indicator for many diseases. In this paper, we …

Water-soluble luminescent nitrogen-doped CDs (N-CDs) having a high QY of 29.83% were
prepared by a one-step microwave-assisted pyrolysis method using ammonium citrate and …

We report a controllable strategy for fabrication of green and blue fluorescent carbon
nanodots (CDs), and demonstrate their applications for pH and Cu 2+ sensing in living cells …

Carbon dots (CDs) were synthesized by the nitric acid oxidation of activated carbon. The
experimental measurements showed that the resulting particles exhibited an average …

Abstract Carbon-dots (CDs)-based fluorescent sensors have been successfully used for
heavy metal ion detection in drinking water, but the following two points hinder their large …

Renewable biowaste-derived carbon dots have garnered immense interest owing to their
exceptional optical, fluorescence, chemical, and environmentally friendly attributes, which …
