Carbon dots and miniaturizing fabrication of portable carbon dot-based devices for bioimaging, biosensing, heavy metal detection and drug delivery applications

Abstract

Carbon dots (CDs), classified as quasi-spherical carbonaceous nanoparticles, have recently gained much attention in wastewater treatment. Their superior distinctive properties, such as non-toxicity, biocompatibility and optical properties, make them a...

Sequential on–off–on detection of Fe2+ and enantiomeric l-lysine with logic gate operation based on fluorescent carbon dots derived from a zinc–amine complex

“…Carbon dots (CDs) with unique fluorescence and ease of synthesis characteristics are considered to be a superior alternative to the conventional fluorescent materials in bioimaging, disease diagnosis and treatment, as well as biosensing applications. [24][25][26] CD-based fluorescent sensors have been successfully applied in the quality control of medicine, biomedical analysis and cancer therapy, as they provide powerful signals for accurate monitoring and obtaining critical information during timely tracking and imaging. 27,28 So far, CDs with various chemical compositions and luminescent features have been facilely synthesized, but the exploration of CD-based fluorescent sensors with capabilities for synergistic and continuous detection of specific metal cations and amino acids is still a great challenge.…”
