Quantum dot (QD)-based probes for multiplexed determination of heavy metal ions

Carbon Dot Therapeutic Platforms: Administration, Distribution, Metabolism, Excretion, Toxicity, and Therapeutic Potential

“…The ability to functionalize their surface with fluorescent probes further allows for ratiometric sensing applications. [50] Research conducted by Jiang et al (2020) demonstrated that solvothermally synthesized heteroatom CDs doped with nitrogen and fluorine (N-CDs-F) were capable of strong absorption in the full spectrum of UV-vis-NIR wavelengths. [48] In vitro, these N-CDs-F showed minimal influence on cell viability and cytotoxicity to HepG2 and HeLa cells following a 24 h incubation period.…”

Construction of DNA Biosensors for Mercury (II) Ion Detection Based on Enzyme-Driven Signal Amplification Strategy

“…This is a challenge for all the researchers in this filed. The third future direction is the simultaneous detection of multiple metal ions [ 98 , 99 , 100 ]. Since more than one toxic metal ion should be detected for ensuring people’s health, simultaneous detection of multiple ions will greatly save cost and time.…”

Green-synthesized, pH-stable and biocompatible carbon nanosensor for Fe3+: An experimental and computational study

“…Thus, low-cost and simple ways of detecting metal ions are highly desirable. In this direction, engineered nanomaterials, for instance, metal and carbon-based quantum dots have been explored as nanoprobes for analysis of various analytes [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. Carbon nanoprobes (carbon dots) have advantage of their benign nature over the metal-based nanoprobes (CdSe/CdTe) as these are associated with environment deterioration and toxicity [ 18 , 19 ].…”
