Carbon nanotube-supported gallium (Ga/CNT) was synthesized and characterized with energy dispersive X-ray scanning electron microscopy, temperature-programmed reduction, temperature-programmed oxidation, and temperature-programmed desorption methods. Characterization results revealed successful preparation of Ga/ CNT. Electrochemical measurements were performed by cyclic voltammetry, differential pulse voltammetry, and electrochemical impedance spectroscopy. The Ga/CNT-based cysteine sensor had a linear response within the range of 0-200 mu M with current sensitivity of 0.0081 mu A/mu M (114 m ...Daha fazlası
In present study, cacao oil-based organo-hydrogels (OHCOs) are synthesized to detect carcinoma antigen 125 (CA-125) in serum medium with electrochemical methods such as cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and differential pulse voltammetry (DPV). OHCOs are prepared by the free radical polymerization reaction with agar, glycerol, and distinct ratios of cacao oil with glutaraldehyde (GA) crosslinker or methylene bisacrylamide (MBA) crosslinker. OHCOs are characterized via Fourier Transform Infrared Spec-troscopy (FT-IR), in different solvent environments and pH ...Daha fazlası
Herein, an electrochemical sensor based 5-(2-phenylbenzo [b] thiophen-3-yl)furan-2-carbaldehyde (PTFC) was developed for the detection of cancer antigen 125 (CA125). Measurements were obtained via cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and differential pulse voltammetry (DPV), and square wave voltammetry (SWV) techniques to investigate features of the electrochemical sensor such as concentration effect of CA125, incubation time, scan rate, limit of quantification (LOQ), limit of detection (LOD), and interference effect of structures found in serum. The sensor wa ...Daha fazlası
