Multifunctional water-soluble luminescent carbon dots for imaging and Hg²⁺ sensing

Abstract

We propose an ingenious method for large-scale fabrication of water-soluble photoluminescent carbon dots (CDs) by a one-step microwave route in the presence of citric acid and ethylenediamine.

Carbon Based Dots and Their Luminescent Properties and Analytical Applications

“…The detection limit of the method was 0.1 µM. Up to now, various sensors for Hg 2+ based on CDs have been fabricated with signal-off process [93,98,115,138,155,167,[223][224][225][226][227]. Most of the experiments were designed reasonably, and the results were good.…”

Comparative study for N and S doped carbon dots: Synthesis, characterization and applications for Fe3+ probe and cellular imaging

“…These encouraging results prompted us to evaluate the feasibility of N-CDs as a new fluorescent marker for living cell imaging [67][68][69]. For effective cellular imaging, it is required that the selected fluorescent marker possesses not only optical merits but also low cytotoxicity [67].…”

“…Meanwhile, they have fascinating properties including outstanding water solubility, good photostability, super biocompatibility, and low toxicity [27][28][29][30] [34], and Bai et al developed a CDs-based fluorescence turnon method for sensitive determination of DNA [35].…”
