A rapid and simple strategy for discrimination and detection of catechol and hydroquinone by fluorescent silicon nanoparticles

Three-dimensional cage zinc triazine framework compound: Fluorescence sensing of aromatic compounds containing NO2/OH groups

“…47 In 2020, Zheng et al synthesized silicon nanoparticles (Si NPs), and their fluorescence was dramatically quenched by hydroquinone (HQ) without a fluorescence shift. 48 In 2021, Hu et al used a high density of boron atoms introduced into nitrogen-doped nanocarbon (BNC) to realize simultaneous detection of HQ and catechol (CC) with a large separation of the peak potential (DE p ) of 111 mV between oxidations of HQ and CC by differential pulse voltammetry. 49 Based on all of the above considerations, along with our own experience in three-dimensional cage MOF with large size conjugate multidentate ligands, we were prompted to undertake the present study on the good fluorescence sensing ability and the lower limit of detection (LOD) for NACs.…”

Green-emitting silicon nanoparticles as a fluorescent probe for highly-sensitive crocin detection and pH sensing

“…As a novel type of environmentally-friendly fluorescent nanomaterials, silicon nanoparticles (SiNPs) have received extensive attention due to their outstanding properties of strong fluorescence, high photo-stability, low toxicity, good biocompatibility and biodegradability. [16][17][18][19][20][21] Owing to their excellent properties, SiNPs have been considered as promising alternatives to toxic heavy metal-containing quantum dots in the field of analysis. In recent years, researchers have developed several methods for synthesizing water dispersible SiNPs, such as post-modification, 22 ultraviolet radiation, 23 microwave 24 and hydrothermal methods.…”

Nitrogen‐rich silicon quantum dots: facile synthesis and application as a fluorescent ‘on–off–on’ probe for sensitive detection of Hg2+ and cyanide ions

“…Furthermore, SiQDs exhibit effective visible emission due to quantum confinement effects and/or surface defects. [20][21][22][23][24] Therefore, SiQDs have emerged as an alternative to toxic QDs and metal nanoclusters because of their superb biocompatibility and low cytotoxicity that make them ideal fluorescent probes for the detection of various analytes. However, no report has referred to the applications of SiQDs for dual detection of Hg 2+ and CN À .…”
