Dual-emission ratiometric fluorescence probe based on copper nanoclusters for the detection of rutin and picric acid

Water Soluble Silicon Nanoparticles as a Fluorescent Probe for Highly Sensitive Detection of Rutin

“…Compared with previously reported methods for rutin detection, the method in this work exhibited a wide linear range and low LOD ( Table 1 ). 27 , 28 , 31 , 32 , 37 , 38 , 45 Moreover, the proposed method is simple, rapid, low cost and high sensitivity.…”

“… 37 Lin et al constructed a dual-emission ratiometric fluorescence probe to selectively detect rutin by the electrostatic interaction of PVP-CuNCs and Rh6G, and the detection limit was 0.84 μM. 38 The above reports provided effective fluorescence methods for rutin detection. Nevertheless, some disadvantages of complicated fluorescent probe preparation process, heavy metals use, narrow linear range, and insufficient sensitivity still existed.…”

“…Sinduja and John synthesized fluorescent carbon dots using asparagine and used them for sensitive detection of rutin in the concentration range of 0.5–15 μM . Lin et al constructed a dual-emission ratiometric fluorescence probe to selectively detect rutin by the electrostatic interaction of PVP-CuNCs and Rh6G, and the detection limit was 0.84 μM . The above reports provided effective fluorescence methods for rutin detection.…”

Construction of ratiometric Si-Mn:ZnSe nanoparticles for the immunoassay of SARS-CoV-2 spike protein

“…They are ideal fluorescent probes and can be used in the field of bioanalytical chemistry [17] . Fluorescence detection mostly adopts single-emission peak probe, which is affected by environmental variation, probe concentration change, and instrumental fluctuation [21] , [22] . Compared with single-emission fluorescence analysis, ratiometric fluorescence method adds internal standard calibration in the detection system, which has the advantages of high stability and low detection background [21] , [23] , [24] .…”

Construction of a Near-Infrared Luminescent 48-Metal Rectangular Zn(II)–Yb(III) Nanocluster with Carbonate Templates for the Dual-Emissive Detection of Rutin as a Medicinal Ingredient

“…10 For example, the luminescence of lanthanide complexes can be in the visible and near-infrared (NIR) ranges and is characterized by narrow emission bands, long decay times, and large effective antennagenerated shifts. 11 Currently, some visible fluorescent copper nanoclusters 12,13 and luminescent lanthanide metal−organic frameworks (Ln-MOFs; Ln = Eu and Tb) 14 have been designed to detect Rut, but so far the use of luminescent highnuclearity lanthanide-based complexes as probes in the Rut detection has not been reported.…”
