Colorimetric and fluorometric dual-channel ratiometric determination of fungicide cymoxanil based on analyte-induced aggregation of silver nanoparticles and dually emitting carbon dots

Experimental synthesis, functionalized modifications and potential applications of monoelemental zero-dimensional boron nanomaterials

“…162 The stereo-complex PEGylated BNPs exhibit oxygen-sensitive uorescence, phosphorescence spectra, and visual detection of oxygen. [163][164][165][166][167][168] Microscope images of both emissions were observed in breast cancer cell lines. Hao et al measured the uorescence spectra of BQDs (probe sonication preparation from bulk boron powder) excited with a 325 nm laser, with the maximal (intense) emission center at 505 nm.…”

Green and facile synthesis of iron-doped biomass carbon dots as a dual-signal colorimetric and fluorometric probe for the detection of ascorbic acid

“…Dual-signal mode can be used to detect the same target by using different output signals, which is more conducive to avoiding false positives and greatly improves the accuracy of the detection results. 20 In addition, it can also take advantage of the differences in the detection ranges of different signals to achieve complementary advantages and improve the detection performance of the new method.…”

Moxifloxacin detection based on fluorescence resonance energy transfer from carbon quantum dots to moxifloxacin using a ratiometric fluorescence probe

“…25 An analytical method for MOX based on detection of CQDs fluorescence has been demonstrated. [26][27][28][29] This method has good selectivity, high stability, and low cost. We noted a sensitive and selective response in the concentration range of 3.3 Â 10 À7 -2 Â 10 À6 M, and the limit of detection was 2.59 nM.…”
