A mechanothermal approach for the synthesis of Fe3O4 nanoparticles as dopant on mesoporous TiO2 for electrochemical determination of catechol

Recent progress in the genotyping of bovine tuberculosis and its rapid diagnosis via nanoparticle-based electrochemical biosensors

“…145 Magnetic NPs for the electrochemical detection of H. tuberculosis Magnetic nanoparticles have useful features such as large surface area, low toxicity, small particle size, and superparamagnetic behavior, which make them an excellent electrode modier for constructing electrochemical sensors. 167,168 An electrochemical sensor based on Fe 3 O 4 incorporated with polypyrrole and a naphthoquinone probe was previously constructed for detecting H. tuberculosis. For modifying the surface of the gold screen-printed electrode with the magnetic particles, a permanent magnet was used, and the potential was swept from −0.4 to +0.8 V vs. Ag/AgCl reference electrode with a scan rate of 50 mV s −1 for ten cycles.…”
