“…The LODs for DLM and FV were determined to be 0.004 mM and 0.26 mM, respectively. In addition, Tables 1 and 2 provide a comparison between the analytical features of the present method and other traditional analytical techniques for the detection of DLM and FV, [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] demonstrating that the MO-CDs-based uorescence method has good selectivity, and a higher sensitivity than the other reported methods. 40,41 Furthermore, the preparation of the MO-CDs did not require any expensive reagents, suggesting the MO-CDs could be used as a sustainable green-uorescent probe for the detection of both DLM and FV in food samples.…”

“…24 Guo, T. et al designed a core-shell upconversion magnetic nanoparticle for the rapid detection of deltamethrin. 25 Lu, N. et al synthesized egg yolk-shell nanostructured Fe 3 O 4 @C nanoparticles for the label free colorimetric detection of H 2 O 2 and glucose. 26 Until now, the poor specificity and selectivity of trace detection and the absence of biosensors for multiplex analyzes were still two vexing problems.…”

“…Biosensing with dispersions of magnetic and nonmagnetic nanoparticles requires sensitive devices capable of detecting single nanoscale objects within complex sample backgrounds [ 4 ]. Conventionally, nonmagnetic nanoparticles are detected and counted using luminescence techniques in which the particles are identified by observing their luminescent surface coatings [ 10 , 14 , 15 , 16 ]. However, the interference produced by the sample’s background often limits the sensitivity of these devices and must be eliminated using time-based techniques or alterations of the analytes or nanoparticle labels [ 17 , 18 ].…”
