Ratiometric electrochemical analysis on a flexibly-fabricated vibratory electrode module for reliable and selective determination of imidacloprid

Towards Development of Molecularly Imprinted Electrochemical Sensors for Food and Drug Safety: Progress and Trends

“…Chlorpromazine (CPZ) is an antipsychotic drug used to treat psychiatric and personality disorders, and clinical monitoring of CPZ is necessary. Liu et al presented Pt/Co 3 O 4 nanoparticles and methylene blue (MB) monomer-based MIPs for selective detection of CPZ [ 74 ]. Wherein, MB molecule in MIPs provides a fixed internal signal, and the signal of CPZ changes with concentrations, which is a typical on/off ratiometric signal output mode.…”

Ratiometric electrochemical detection of tryptophan based on ferrocene and carboxylated-pillar[6]arene hybrid metal–organic layers

“…For example, Zhang's group reported that the relative standard deviations (RSDs) of single-signal sensor constructed from b-cyclodextrin (b-CD) or prussian blue (PB) is not as low as that of the ratiometric electrochemical sensor constructed based on b-CD and PB for imidacloprid sensing. 7 In addition, they found that the ratiometric electrochemical analysis could also improve the longterm stability of the sensor. Consequently, the ratiometric strategy could effectively reduce the interferences from internal or external factors and improve the robustness and precision of detections.…”

A DNA tetrahedral nanomaterial-based dual-signal ratiometric electrochemical aptasensor for the detection of ochratoxin A in corn kernel samples

“…Hence, the reliability and accuracy of the analysis are improved. 24,25 Metal-organic frameworks (MOFs) are ordered network structures formed by the combination of organic bridging ligands and inorganic metal ions. 26 Numerous studies have demonstrated significant advantages of MOFs in sensing, 27 gas storage, 28 and catalysis 29 ascribed to their porous structure and large specific surface area.…”
