Fluorescent carbon nanoparticles for the fluorescent detection of metal ions

Fluorescence resonance energy transfer-based ratiometric fluorescent assay for highly sensitive and selective determination of sulfide anions

A novel and effective ratiometric fluorescence strategy was developed for rapidly, sensitively and selectively probing sulfide anions (S²⁻).

Hydroxyl-rich C-dots synthesized by a one-pot method and their application in the preparation of noble metal nanoparticles

Hydro-rich C-dots were used as both the reducing and stabilizing agent in the preparation of noble metal nanoparticles (AuNPs, AgNPs and Au@AgNPs) for the detection of glucose.

An ionic liquid promoted microwave-hydrothermal route towards highly photoluminescent carbon dots for sensitive and selective detection of iron(iii)

Carbon dots with a high photoluminescence efficiency of ∼22.58% are obtained by a facile microwave-hydrothermal treatment of rice straw with the presence of ionic liquid.

Detection of thiocyanate through limiting growth of AuNPs with C-dots acting as reductant

We have found that hydroxyl-rich carbon dots (C-dots) have the ability to reduce Au³⁺to form gold nanoparticles (AuNPs) which can be used as an optical sensor to detect SCN⁻in raw milk with satisfactory results.

Recent developments in carbon nanomaterial sensors

The structural diversity of carbon nanomaterials provides an array of unique electronic, magnetic and optical properties, which when combined with their robust chemistry and ease of manipulation, makes them attractive candidates for sensor applications. In this review recent developments in the use of carbon nanoparticles and nanostructures as sensors and biosensors are explored.

Facile synthesis of polyaniline/carbon dot nanocomposites and their application as a fluorescent probe to detect mercury

Novel polyaniline/carbon dot nanocomposites have been synthesized using a simple method, and a PANI/Cdot “off–on” fluorescent probe has been constructed for the simple, ultrasensitive and selective detection of Hg²⁺ in aqueous media.
