An easy synthesis of nitrogen and phosphorus co-doped carbon dots as a probe for chloramphenicol

Abstract

The spontaneous synthesis of nitrogen and phosphorus co-doped carbon dots was reported, and they were used as a probe for chloramphenicol.

Chloramphenicol-activated electro-chemiluminescent behavior of BNQDs-Ru(phen)3 2+ system for ultra-sensitive sensing of chloramphenicol in pharmaceutical and milk samples

“…system for ECL detection of CAP exhibits a wider linear range and a lower detection limit, comparing with the previous results (table 1) [43][44][45][46].…”

Water Soluble PMPC-Derived Bright Fluorescent Nitrogen/Phosphorous-Doped Carbon Dots for Fluorescent Ink (Anti-Counterfeiting) and Cellular Multicolor Imaging

“…The shoulder peak at 260 nm is ascribed to the n − π* transition from the functional groups such as C=O [ 56 , 57 ]. The shoulder peak around 320 nm is responsible for exciting surface defects because of the presence of hetero atoms in P-CDs [ 58 , 59 ]. An enlarged UV-Vis spectrum of P-CDs ( Figure 5 a) between the range of 240–420 nm was provided for clear observation of the shoulder peak (320 nm), shown in Figure S5 .…”

Simple and cheap preparation of fluorescence paper sensor based in carbon dot for visual detection of chloramphenicol

“…[ 20 ] The fluorescence of N,P‐CDs (arginine and P 2 O 5 ) was selectively quenched by CAP with a short response time, and LOD = 0.12 ppm. [ 34 ]…”

“…[20] The fluorescence of N,P-CDs (arginine and P 2 O 5 ) was selectively quenched by CAP with a short response time, and LOD = 0.12 ppm. [34] The fluorescence quenching process of a-and b-CDs by CAP, could be reported for the IFEs (inner filter effects) mechanism. From the spectra in Figure 8, we could see a good spectral overlap between the absorption spectrum of CAP and the excitation spectra of a-and b-CDs, suggesting that the fluorescence quenching might be related to IFE.…”
