Electrochemical sensor based on micromotor technology for detection of Ox-LDL in whole blood

Intelligent sensing based on active micro/nanomotors

“…The same group modified antibodies specific to oxidized low-density lipoprotein (Ox-LDL) onto the surface of magnesium (Mg)–Fe 3 O 4 @Prussian blue micromotors, creating an electrochemical sensor for Ox-LDL. 118 The movement of these micromotors enhances the capture of Ox-LDL, while the catalytic effect of Prussian blue on H 2 O 2 reduction enables the determination of current signals. However, the presence of Ox-LDL impedes electron transfer, leading to a decrease in the value of the current signal.…”

Recent advancements in Mg-based micromotors for biomedical and environmental applications

“…7c). 58 Wan and Shen et al prepared aldehyde-functionalized Mg-based Janus micromotors using PMMA as the substrate and an aldehydeamine condensation reaction to modify Fe 3 O 4 /polydopamine/ anti-epithelial cell adhesion molecule (EpCAM). Tumour cells were also captured and detected by magnetic glass electrodes.…”

“…If Mg microspheres are dispersed on the PMMA, the micromotors can be collected by dissolving the PMMA film. 58,59 Wang et al and Zhang et al coated red blood cell (RBC) membranes on the surface of Mg-based micromotors to realize micromotors with great biocompatibility and the ability to simulate cell motion. A layer of Mg microparticles was dispersed on a parafilm, and then, Au and alginate (ALG) were deposited on the surface of Mg.…”

“…They found that the current increases with the number of micromotors, and this method involving micromotors is faster and more accurate than static detection is, confirming its great All rights reserved. 58 application prospects in biosensing. 76 Furthermore, Mou and Zhou et al prepared Mg-Fe 3 O 4 @PB@Ab@BSA Janus micromotors to detect oxidized low-density lipoprotein (Ox-LDL) in human blood by electrochemical sensing.…”

Effect of magnetic field on voltammetric sensor for electrolytic concentration measurement and electrode–electrolyte interface model based on a novel geometry

“…Most of the recent works related to voltammetry focuses on detecting organic solutes in electrolytes with different improvements in electrodes [24,27]. A few of the research works focus on the technologies like tomography [28], Electrochemical Impedance Spectroscopy [29], chronoamperometry [30], while some others focus on input signal models [31]. From a physical perspective, the impact of electromagnetic waves on conventional electrode models has not been explored for nonmagnetic electrolytes [23].…”
