Reed-derived fluorescent carbon dots as highly selective probes for detecting Fe³⁺ and excellent cell-imaging agents

Abstract

A highly selective and sensitive fluorescent probe for detecting Fe3+, carbon dots (CDs), was prepared with renewable reed naturally containing C, N, O, and S elements as a green and eco-friendly carbon source by a simple hydrothermal process.

Photophysical Investigation of a Benzimidazole Derivative and Its Applications in Selective Detection of Fe3+, Thermosensing and Logic Gates

“…Fe 3+ has shown a high chelating effect towards these functional groups, hence considerable quenching was observed. [23] There is also a possibility of non-radiative transfer of energy or electrons from excited states of sensor1 to half filled 3d 5 states of Fe 3+ .…”

Cross-Linked Polyamide Chains Enhanced the Fluorescence of Polymer Carbon Dots

“…Carbon dots (CDs) are a special kind of fluorescent nanoparticles with a diameter less than 10 nm. , CDs have attracted great attention in recent years for their unique properties, such as high aqueous solubility, good biocompatibility, and resistance to photobleaching, − and have been intensively studied in the fields of sensors, − light-emitting devices, electrochemical analysis, bioimaging, − drug delivery, and photocatalysis. , Great effort has been devoted to synthesizing CDs with photostability and photoluminescence (PL). ,, However, a comprehension of the general fluorescence phenomenon still remains unclear, which hinders advances in the design, preparation, and application of CDs. − …”
