Fabrication of a sensitive electrochemical sensor based on hybrid polyamide/chromotropic acid nanofibers electrospun on glassy carbon electrode for Hg2+ sensing in drinking water and canned fish samples

Comparison of the analytical performance of two different electrochemical sensors based on a composite of gold nanorods with carbon nanomaterials and PEDOT:PSS for the sensitive detection of nitrite in processed meat products

“…From the slope of I p versus v (gure not shown), the surface coverage of nitrite adsorbed on the surface of AuNRs/ErGO/PEDOT:PSS/GCE and AuNRs/MWCNT/PEDOT:PSS/GCE were calculated to be 1.45 × 10 −6 and 1.81 × 10 −6 mol cm −2 , respectively, which are comparable to those previously reported. 80,81 3.5. Kinetics of the electrocatalytic activity of nitrite oxidation for both modied electrodes…”

Intelligent point of care test for food safety via a smartphone

“…Moreover, multiple heavy metals can be simultaneously qualified via a DPV POCT, providing LODs of 0.296 (Cd), 0.055 (Cu), 0.351 (Hg), and 0.025 (Pb) μmol/L in tap water [115]. Morawska et al [116] established a SWV method to explore the influence factors such as electrolyte pH, composition, square wave parameters, and scanning rate. Nanomaterials have high specific surface area characteristics, making the electrode modified with nanomaterial have better signal quality [117].…”

A novel electrochemical sensing method based on an amino-functionalized MXene for the rapid and selective detection of Hg2+

“…[1][2][3][4] Recognized as one of the top ten chemicals of concern by the World Trade Organization (WTO), mercury has the ability to accumulate in living organisms and can inict damage on genetic, reproductive, renal, neurological, and cardiovascular systems. 2,[4][5][6][7][8][9] As such, detecting the presence of Hg 2+ in water is of vital importance to both environmental preservation and human wellbeing. Currently, the most widely employed techniques for detecting Hg 2+ include inductively coupled plasma mass spectrometry, 10 atomic uorescence spectrometry, 11 atomic absorption spectroscopy, 12 atomic emission spectrometry, 13 uorescence, 14 electrochemical methods, 15 etc.…”
