Stability of carbon quantum dots: a critical review

Abstract

Carbon quantum dots (CQDs) are fluorescent carbon nanomaterials with unique optical and structural properties. The detailed stability analysis of CQDs is very much needed for their commercial applications.

Biogenic carbon dots: a novel mechanistic approach to combat multidrug-resistant critical pathogens on the global priority list

“…19 According to studies, solid CDs remain stable up to 400 °C, with minimal weight loss at temperatures below 100 °C. 32 Additionally, CDs synthesized through the green hydrothermal process displayed notable pH stability, making them well-suited for diverse environmental conditions. 11 The application of CDs as highly sensitive fluorescent detectors in ionic solutions demonstrated their versatility in detecting various ions, such as Fe ions, in aquatic solutions.…”

“…This decrease in toxicity under prolonged exposure to UV light can be attributed to a combination of factors. First, long-term exposure of CD to 365 nm UV light led to a gradual decrease in their fluorescence ability . Second, extended irradiation caused changes in the surface characteristics of the CD-500 membrane (as seen in Figure S8), creating an environment conducive to the growth of bacterial colonies. , These changes affected the mechanism by which CD imparts toxicity, contributing to the observed decline in antibacterial performance.…”

Carbon dots@noble metal nanoparticle composites: research progress report

“…In contrast, CDs have better thermal stability, and no light loss was observed at a constant high temperature (80 °C) for 30 min. 146 Therefore, the combination of CDs is likely to promote the thermal stability of metal nanoparticles to a certain extent. Usually, the stability is determined by applying a certain intensity of light and heat to the material and observing the property changes within a certain period.…”
