Paper carbon dot based fluorescence sensor for distinction of organic and inorganic sulphur in analytes

Abstract

In this work a paper carbon dot (PCDs) based fluorescence sensor was developed which can distinguish between the organic and inorganic sulphur in analytes.

Novel β-cyclodextrin doped carbon dots for host–guest recognition-assisted sensing of isoniazid and cell imaging

“…In recent years, uorescent assays have attracted considerable attention with merits of simplicity, rapid response, high selectivity and sensitivity. 5 Compared to conventional uorescent materials, such as organic uorescent dyes, metal nanoclusters and quantum dots, carbon dots (CDs) are perceived to be promising nanomaterials for the construction of uorescent sensors, 6,7 given their excellent uorescence performance, easy preparation, high water-solubility, chemical inertness, good photostability and low cytotoxicity. [8][9][10][11][12] So far, CDs based sensors have been successfully applied in the analysis of various compounds.…”

Carbon Dot based Fluorescence sensor for Retinoic acid

“…But these fluorescent probes come with many disadvantages like toxicity, high cost etc . As fallout recently carbon dots (CDs) which are carbon nanoparticles of size below 10 nm have gained a lot of applaud due to their various properties like easy fuctionalization, cost effective, low toxicity, easy synthesis etc ,,. Ease of surface functionalization of CDs has made it extremely efficient in using CDs in the detection of various biological compounds .…”
