Nanotextured La0.95Ce0.05MnO3/GCE assemblage for ultrasensitive and precise electrochemical detection of arsenic (III) at neutral pH

An iron metal–organic framework-based electrochemical sensor for identification of Bisphenol-A in groundwater samples

“…47–50 It is feasible to electrochemically enhance the electroactive region of the electrodes and electron shift proclivity via electro-anodizing the electrode's outer layer at regulated potentials, which depends on impedance measurements and CVs. 45,51,52 Based on the findings, BPA could be verified with the developed electrode materials.…”

Borophene Nanosheet-Based Electrochemical Sensing toward Groundwater Arsenic Detection

“…To obtain an arsenic concentration in real samples, an actual water matrix from Kolkata, West Bengal, and India’s interior, a random sampling strategy was preferred. For the assessment, a 1 mL real sample was mixed with As­(III) standard and diluted in 5 mL of pH-appropriate PBS (0.1 M) solution …”

“…For the assessment, a 1 mL real sample was mixed with As(III) standard and diluted in 5 mL of pHappropriate PBS (0.1 M) solution. 45 ■ RESULTS AND DISCUSSION those in graphene, atomic displacements in the direction of atomic ridges would result in more Raman peaks. Furthermore, with borophene sheets, we were able to produce prominent Raman peaks at distances of 330, 408, 697, 805, and 1129 cm −1 (Figure 1A).…”

Construction of a novel cuboid-shape Mn-Urea nanozyme with arsenic(v)-enhanced oxidase-like activity as a colorimetric probe for the selective detection of inorganic arsenic

“…To date, traditional instrumental methods, including inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectroscopy (AAS), and atomic fluorescence spectroscopy (AFS), have been frequently applied in the quantitative analysis of inorganic As. [6][7][8] However, these instrument-based methods for As detection require rigorous lab environment, expensive instruments and professional operation, 9,10 which are unable to meet the requirements of convenient and quick testing. To address these issues, nanozyme-based optical analytical methods with easy operation and high sensitivity, such as colorimetry 5,11 and fluorometry, 12,13 are employed in the detection of inorganic As.…”
