In this study, Anacardium occidentale (A. occidentale) nut skin waste (cashew waste) was used as a raw material to synthesize functionalized carbon nanodots (F-CNDs). A. biomass-derived F-CNDs were synthesized at low temperature (200 °C) using facile, economical hydrothermal method and subjected XRD, FESEM, TEM, HRTEM, XPS, Raman Spectroscopy, ATR-FTIR, Ultraviolet-visible (UV–vis) absorption fluorescence spectroscopy determine their structures, chemical compositions, optical properties. The analysis revealed that dispersed, hydrophilic had mean diameter of 2.5 nm. XPS ATR-FTIR showed crystalline core an amorphous surface decorated with –NH2, –COOH, C=O. addition, quantum yield 15.5% exhibited maximum emission 406 nm when excited 340 Human colon cancer (HCT-116) cell assays readily penetrated into the cells, outstanding biocompatibility, high photostability, minimal toxicity. An MTT assay viability HCT-116 cells incubated for 24 h in presence μg mL–1) exceeded 95%. Furthermore, stimulated by filters three different wavelengths (405, 488, 555 nm) under laser scanning confocal microscope, containing emitted blue, red, green, respectively, which suggests might be useful biomedical field. Thus, we describe production fluorescent nanoprobe from cashew potentially suitable bioimaging applications.

Advances on chalcogenide quantum dots-based sensors for environmental pollutants monitoring

The Science of The Total Environment, Год журнала: 2024, Номер 931, С. 172848 - 172848

Опубликована: Май 3, 2024

Water contamination represents a significant ecological impact with global consequences, contributing to water scarcity worldwide. The presence of several pollutants, including heavy metals, pharmaceuticals, pesticides, and pathogens, in resources underscores pressing concern, prompting the European Union (EU) establish Watch List monitor level these substances. Nowadays, standard methods used detect quantify contaminants are mainly liquid or gas chromatography coupled mass spectrometry (LC/GC–MS). While methodologies offer precision accuracy, they require expensive equipment experienced technicians, cannot be on field. In this context, chalcogenide quantum dots (QDs)-based sensors have emerged as promising, user-friendly, practical, portable tools for environmental monitoring. QDs semiconductor nanocrystals that possess excellent properties, demonstrated versatility across various sensor types, such fluorescent, electrochemical, plasmonic, colorimetric ones. This review summarizes recent advances (2019–2023) use sensing, highlighting development capable efficiently anions, endocrine disrupting compounds, organic dyes, toxic gases, nitroaromatics, pathogens.
