Modification of electrodes with polymer nanocomposites: Application to the simultaneous determination of Zn(II), Cd(II), and Cu(II) in water samples

Novel Aspects in the Voltametric Determination of Heavy Metals: A Minireview

“…A buffer solution of 0.25 M acetate at pH 4.5 was used as electrolyte. According to the results, the proposed method showed sufficient LOD (0.53 μg/L, 1.52 μg/L, 0.23 μg/L respectively), sensitivity, selectivity and reproducibility for the detection of these metals in water samples [79].…”

A novel electrochemical biosensor based on WO3@AuNPs and HBP@BIBB macromolecule-triggered ATRP for DR1 detection

“…7 Electrochemical sensors are based on the recognition of the target by biomolecules, and the target is detected by applying a potential on the working electrode and recording the generated redox current. 8 In order to achieve the accurate detection of low-level biomarkers in the early stage of the disease, a variety of signal amplification strategies have been proposed to improve the sensitivity of the sensor, including enzyme catalysis, 9 nanomaterials, 10 polymerization, 11 etc. Nanomaterial-based amplification techniques have received widespread attention in the past few years due to the characteristics of nanomaterials, including high specific surface areas, high conductivity, good biocompatibility and easy modification.…”
