Selective identification of p-nitroaniline by bromine-mediated polarization of carbon dots

Abstract

A fluorometric method based on boron, bromide-codoped carbon dots (BBCNs) was firstly developed for the highly selective detection of p-nitroaniline (PNA) in wastewater samples. Note that the introduction of bromine...

Preparation and utilization of carbon dots as a nanoprobe for sensitive detection of tartrazine and palladium (ii)

“…4C), implying that electronic transfer is the mechanism responsible for the Pd( ii )-induced quenching of the FL of the Cdots. 14,20 According to the above results and discussion, the effects of Trz and Pd( ii ) on the FL of the Cdots are due to FRET and electronic transfer mechanisms, respectively.…”

“…In recent decades, carbon-based luminescent nanomaterials (CLNMs) have emerged as a novel and markedly important class of fluorescent probes with distinctive optical and surface physicochemical properties, allowing them to have many applications in the field of analysis. 14,15 Excitingly, the functionality of CLNMs ( i.e. , surface functional groups) can be effectively tuned by handpicking various precursors to achieve monitoring of selected analytes with high selectivity and sensitivity.…”

“…CO and CN). 14,26 Upon excitation with a 325 nm-wavelength beam (Fig. 2A, curve b), a strong FL emission peak appears at 400 nm (Fig.…”
