Green synthesis of carbon dots by celery leaves for use as fluorescent paper sensors for the detection of nitrophenols

Abstract

Schematic of synthesis CDs, extending to paper sensor and using in detection.

Recent Advances and Applications in Paper-Based Devices for Point-of-Care Testing

“…In addition, μPads have been used for the rapid detection of chemical molecules (e.g. glucose, dipicolinate (PDA) and so on [171][172][173][174][175]. On the basic of an Eu (III)-EDTA complexes functionalized poly(diacetylene acid) derived liposomes, a novel ratiometric FL detection system was established on a paper chip for the visual detection of PDA [171].…”

Green synthesis of carbon dots and their applications

“… 38 Moreover, hybrid green syntheses have also been performed through the mixture of renewable raw materials and renewable refined compounds, such as the use of celery leaves and l -glutathione in a hydrothermal CD synthesis. 39 …”

Carbon Dots: An Excellent Fluorescent Probe for Contaminant Sensing and Remediation

“…Thus, though the preparation of CDs with selective contaminant detection among other analytes is challenging, surface modification, functionalization, and doping are few ways to improve the selectivity of CDs. [20] Small 2022, 18, 2105579 Ficus bengalensis 2.28 Blue-green [37] Celery leaves -Blue [63] Pristine CDs, [65] functionalized CDs, [66] and the composites of CDs [67] have been utilized by different scientists in sensing a wide variety of contaminants. The interactions between the analyte and the CDs provide the basis for the sensing concept.…”
