Recent Advances in the Applications of Carbon Nanostructures on Optical Sensing of Emerging Aquatic Pollutants

Abstract

In recent years, optical sensing based on nanomaterials has emerged as a prospective strategy for monitoring environmental pollution in water. In this context, carbon nanostructures have received increasing attention due to their unique optoelectronic and physiochemical properties. To this end, nanocarbon such as carbon nanotubes, graphene, and carbon dots have been used to develop proof‐of‐concept opto‐chemical sensors for emerging aquatic contaminants, including pesticides, bacterial pathogens, and pharmaceuticals residues. These optical sensors have attracted significant research interest in nanotechnology, material science, and the detection of aquatic pollutants. However, the practical application for detecting contaminants is still limited because of cost‐effectiveness, sensitivities, and selectivity toward the diverse pollutants. This review examines the current trends and challenges in designing and applying carbon nanostructure‐based optical sensors for detecting aquatic contaminants. Finally, a critical perspective on the field and future research directions is provided.

WITHDRAWN: Development of extremely luminescent B, N-CQDs as a probe for the detection of antibiotics and phenol derivatives in aquatic applications

“…Doping of CQDs to demonstrate high performance in terms of stability and optical features is one of the most recent technologies. More study is needed on lowcost, simple, and effective strategies for detecting a wide range of undesired pharmaceutics and environmental contaminants such as pesticides, antibiotics, phenolic chemicals, poly-aromatic hydrocarbons, and heavy metal ions 5 .…”

Carbon Materials for Organophosphate Pesticide Sensing

“…Carbon nanostructures possess inimitable optoelectronic and physiochemical properties. Due to this, materials such as carbon nanotubes, graphene, and carbon dots have been used to develop opto-chemical sensors for many environmental contaminants (pesticides, microbiological pathogens, pharmaceutics) [17]. Remarkable properties and various carbon materials made them unavoidable in developing powerful sensor devices nowadays.…”

Pure and doped carbon quantum dots as fluorescent probes for the detection of phenol compounds and antibiotics in aquariums

“…Most of the reported doped-CQDs are produced using two or more expensive reaction precursors, which may complicate purification 20 . Therefore, finding a simple, readily available, low-cost precursor to make two different kinds of heteroatom-doped CQDs is still a challenge.…”
