An insight of light-enhanced electrochemical kinetic behaviors and interfacial charge transfer of CuInS2/MoS2-based sensing nanoplatform for ultra-sensitive detection of chloramphenicol

Electrochemical Kinetic Behaviors and Sensing Performance of Au@ZIF-8 and Ag@ZIF-8 Nanocomposites-Based Platforms Towards Ultrasensitive Detection of Chloramphenicol

“…As previously mentioned, the electrochemical redox reaction of CAP on the proposed electrodes followed a typical adsorption-controlled process. Consequently, using the Cottrell's law, the diffusion coefficient (D) of CAP molecules at the electrolyte/electrode interface was determined via the recorded current response under mass transport-limited conditions: 33,34,38…”

Enhanced sensing performance of carbaryl pesticide by employing a MnO2/GO/e-Ag-based nanoplatform: role of graphene oxide as an adsorbing agent in the SERS analytical performance

“…Based on these linear relationships, the adsorption capacity ( Г ) of CBR on the modified electrode surfaces was also determined through the equation: 34 I p = n 2 F 2 AГν /4 RT . According to that, the Г values of CBR were estimated to be around 19.4 × 10 −12 , 20 × 10 −12 , and 25.7 × 10 −12 mol cm −2 for e-Ag_SPE, MnO 2 /e-Ag_SPE, and MnO 2 /GO/e-Ag_SPE, respectively.…”

“…Based on these linear relationships, the adsorption capacity (G) of CBR on the modied electrode surfaces was also determined through the equation: 34 As CBR is a naphthalene-derivatized carbamate, the characteristic peaks of CBR were dominated by ones associated with naphthalene and the carbamate vibrational mode. The band at 453 cm −1 was assigned to the low-frequency C-C bending modes.…”

Visible Light as a Promising Signal Amplification Tool for the Efficient Electrochemical Detection of Azithromycin Antibiotic by Using Photoactive Spinel Nickel Ferrite Nanoflakes

“…magnetic field and light field in enhancing the analytical performance of electrochemical nanosensors. [9][10][11] The obtained results suggest that external fields are flexible, efficient, and controllable ways to enhance the electrochemical activity without changing the bulk characteristics of the pristine nanomaterials.…”
