“…EIS is a technique that is frequently used in analyzing materials in areas such as biology, electrochemistry, medicine, material science, and sensor. The Nyquist plots obtained from EIS data take place at a linear cross-section and a semicircular area expressing a diffusion-controlled reaction and load transfer resistance ( R ct) on the material surface. − The Nyquist plots are given in Figure c. A gradual decrease between −0.6 (59.82 Ω) and 0.0 (9.55 Ω) potentials and a gradual increase between 0.0 (9.55 Ω) and 0.5 (75.23 Ω) potentials were observed in the semicircular area.…”

To reduce the high mortality rates caused by ovarian cancer, creating high-sensitivity, quick, basic, and inexpensive methods for following cancer antigen 125 (CA-125) levels in blood tests is of extraordinary significance. CA-125 is known as the exclusive glycoprotein employed in clinical examinations to monitor and diagnose ovarian cancer and detect its relapses as a tumor marker. Elevated concentrations of this antigen are linked to the occurrence of ovarian cancer. Herein, we designed organohydrogels (ONOHs) for identifying the level of CA-125 antigen at fast and high sensitivity with electrochemical strategies in a serum medium. The ONOH structures are synthesized with glycerol, agar, and glutaraldehyde and at distinct ratios of onion oil, and then, the ONOHs are characterized with Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). Electrochemical measurements are performed by cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS) in the absence and presence of CA-125 on the designed ONOHs. For the prepared ONOH-3 electrode, two distinct linear ranges are determined as 0.41−8.3 and 8.3−249.0 U/mL. The limit of quantitation and limit of detection values are calculated as 2.415 and 0.805 μU/mL, respectively, (S/N = 3). These results prove that the developed electrode material has high sensitivity, stability, and selectivity for the detection of the CA-125 antigen. In addition, this study can be reasonable for the practical detection of CA125 in serum, permitting early cancer diagnostics and convenient treatment.

“…Fuel cells are the devices that convert the chemical energy in fuel to electrical energy 1 . Recently, many studies have been conducted on fuels such as formic acid, 2,3 glucose, 4 ethanol, 5 methanol, 6 and hydrazine 7 . Herein, glucose is the most interesting fuel for liquid fuel cell technology with its superior properties like its high energy density, abundance in nature, easy transportation, safety, and non‐toxicity 8‐10 .…”

Herein, carbon nanotube (CNT) supported ruthenium (Ru), iridium (Ir), and copper (Cu) catalysts at 0.1 to 20 wt% metal loading are prepared by the NaBH4 reduction method for glucose electrooxidation reaction (GER). These catalysts are successfully characterized by X‐ray diffraction, scanning electron microscope, and N2 adsorption‐desorption measurements. Voltammetric measurements of these catalysts are taken using cyclic voltammetry and chronoamperometry techniques. The crystallite sizes of these catalysts are calculated as 2.53 nm for Ru/CNT, 2.94 nm for Ir/CNT, and 13.06 nm for Cu/CNT by using Scherrer equation. For GER, 10% Ru/CNT, 0.1% Ir/CNT, and 0.5% Cu/CNT catalysts have high current densities as 1.86 mA cm−2 (160.6 mA mg−1 Ru), 3.03 mA cm−2 (23 857.2 mA mg−1 Ir), and 1.12 mA cm−2 (1768.8 mA mg−1 Cu), respectively. These catalysts have also good stability. Results reveal that 10% Ru/CNT, 0.1% Ir/CNT, and 0.5% Cu/CNT catalysts are promising catalysts as direct glucose fuel cell anode catalysts.
