Abstract
A rapid, facile and ultrasensitive fluorescence sensing system based on beer-derived nitrogen, phosphorus co-doped carbon quantum dots (N, P-CQDs) for the detection of ascorbic acid (AA) in fruits was proposed. N, P-CQDs were successfully synthesized by one-step hydrothermal method, which afforded a high quantum yield (21.7 %), and showed the fluorescence with a maximum emission wavelength of 450 nm at an excitation wavelength of 370 nm. Further, N, P-CQDs were employed as an efficient sensor for ultrasensitive Fe3+-detection at concentrations ranging from 1-20 µM and 100-300 µM, respectively. N, P-CQDs@Fe3+ showed a high sensitivity and selectivity for AA detection. A linear response range for AA was obtained from 1 to 200 µM with limit of detection of 0.84 µM was obtained for AA. The result of MTT test showed that N, P-CQDs exhibit low toxicity, providing fast, accurate and less toxic route for testing AA in the food analysis fields.

Nanocomposites of boronic acid-functionalized magnetic multi-walled carbon nanotubes with flexible branched polymers as a novel desorption/ionization matrix for the capture and direct detection of cis-diol-flavonoid compounds coupled with MALDI-TOF-MS. JOURNAL OF HAZARDOUS MATERIALS 2022; 429:128055.

Abstract
Novel boronic acid-functionalized magnetic multi-walled carbon nanotubes with flexible branched polymer (Fe3O4@MWCNTs@ε-PL@BA) nanocomposites were fabricated and applied as the desorption/ionization matrix for the MALDI-TOF-MS determination of low molecular weight flavonoids. The prepared nanocomposite was systematically characterized by various techniques. Compared to the traditional organic matrix, the proposed Fe3O4@MWCNTs@ε-PL@BA matrix has excellent ionization efficiency and low-background noise interference due to the MWCNTs unique electron-phonon interaction and the high introduction density of boronic acid functional groups. Good sensitivity and ultra-high salt tolerance of the Fe3O4@MWCNTs@ε-PL@BA-assisted MALDI-TOF-MS were permitted for the determination and quantification of flavonoids in actual samples. Noticeably, the limits of detection (LODs) for the target flavonoids were in the range 17-33 nM. The relative standard deviations (RSDs) of spot-to-spot and sample-to-sample (n = 10) were ≤ 9.8% and ≤ 10.1%, respectively. Furthermore, the wide linear ranges (0.1 - 500 µg/mL) and satisfactory calibration plot coefficients (R2 > 0.99) of flavonoids were achieved by MALDI-TOF-MS with the Fe3O4@MWCNTs@ε-PL@BA matrix. Good recoveries (92-105.5%) were achieved for the target flavonoids in practical food samples. Hence, the prepared Fe3O4@MWCNTs@ε-PL@BA nanocomposites have applications in the selective and efficient capture of target flavonoids active biomolecules coupled with MALDI-TOF-MS determination in actual samples.

Organic Molecules. CURR ANAL CHEM 2022. [DOI: 10.2174/1573411017999210120180236] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022]
Abstract
Background:
Fluorescence-based sensing is considered highly sensitive and fluorescent probes with improved
properties are always desired. Fluorescent carbon dots (CDs) are newly emerging quasi-spherical nanoparticles of less than
10 nm in size and belong to the carbon nano-material’s family. CDs have great potential as fluorescent probes and currently
are under open deliberation by the researchers due to their striking properties such as low environmental hazard, high
selectivity, greater sensitivity, good biocompatibility, tunable fluorescent properties and excitation dependent multicolor
emission behavior.
Introduction:
This review demonstrates various available methods for fabrication of fluorescent CDs, capping of CDs and
characterization with various techniques including UV-visible, FT-IR, and TEM. Analytical applications using CDs for the
sensing of small organic molecules, specifically nitroaromatic compounds in the environmental samples are complied.
Methods:
The review covers literature related to synthesis and characterization of carbon dots. It includes around 171
research articles in this field.
Results:
Carbon dots can be synthesized using numerous routes. In all cases CDs possess spectral properties with little
variation in wavelength maxima. Optical properties of CDs can be tuned by compositing these with metallic quantum dots
or by modifying their surface with desired functionalities. HR-TEM is needed to see the morphology and size of particles
whereas UV-Visible and FTIR are indispensable tools for this kind of research. These particles are successfully applied to
sense small molecules in some matrices.
Conclusion:
Carbon dots are bright stars in fluorescent sensing of small molecules. However, more research is needed to
determine small organic molecules in diversified areas of analysis.

Abstract
Phenolic compounds are secondary metabolites frequently found in plants that exhibit many different effects on human health. Because of the relevant bioactivity, their identification and quantification in agro-food matrices as well as in biological samples are a fundamental issue in the field of quality control of food and food supplements, and clinical analysis. In this review, a critical selection of sensors and biosensors for rapid and selective detection of phenolic compounds is discussed. Sensors based on electrochemistry, photoelectrochemistry, fluorescence, and colorimetry are discussed including devices with or without specific recognition elements, such as biomolecules, enzymes and molecularly imprinted materials. Systems that have been tested on real matrices are prevalently considered but also techniques that show potential development in the field.

Abstract
: In this work the influence of carbon nano-dots (CNDs) on absorption of ultra violet (UV) spectra in hybrid PVA based composites was studied. The FTIR results reveal the complex formation between PVA and CNDs. The shifting was observed in XRD spectrum of PVA:CNDs composites compared to pure PVA. The Debye-Scherrer formula was used to calculate the crystallite size of CNDs and crystalline phases of pure PVA and PVA:CNDs composites. The FESEM images emphasized the presence and dispersion of C-dots on the surface of the composite samples. From the images, a strong and clear absorption was noticed in the spectra. The strong absorption that appeared peaks at 280 nm and 430 nm can be ascribed to the n-π* and π-π* transitions, respectively. The absorption edge shifted to lower photon energy sides with increasing CNDs. The luminescence behavior of PVA:CNDs composite was confirmed using digital and photo luminescence (PL) measurements. The optical dielectric constant which is related to the density of states was studied and the optical band gap was characterized accurately using optical dielectric loss parameter. The Taucs model was used to determine the type of electronic transition in the samples.
