Novel gallium-based voltammetric sensor for sensitive detection of cysteine

Nahit AKTAŞ

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 ...More

Nanostructured electrochemical cysteine sensor based on carbon nanotube supported Ru, Pd, and Pt catalysts

Nahit AKTAŞ

At present, a voltammetric L-Cystein (Cys) sensor is developed based on carbon nanotube (MWCNT) supported Ru, Pd, and Pt monometallic catalyst modified glassy carbon electrodes (GCE). Ru/MWCNT, Pd/MWCNT, and Pt/MWCNT catalysts are prepared via sodium borohydride reduction method and characterized with advanced surface analytical techniques as inductively coupled plasma mass spectrometry (ICP-MS), N2 adsorption-desorption, X-ray diffraction (XRD), and transission electron microscopy (TEM). Characterization results reveal that these catalysts are succesfully sythesized at desired metal loadings. ...More

Electrochemical Cysteine Sensor on Novel Ruthenium Based Ternary Catalyst

Nahit AKTAŞ

At present, a voltammetric L-Cystein (Cys) sensor is developed based on carbon nanotube (CNT) supported Ru-Mo-Pd trimetallic catalyst modified glassy carbon electrodes (GCE). Firstly, Ru-Mo/CNT catalysts are prepared via sodium borohydride reduction method and following this Ru-Mo/CNT modified GCE electrode is prepared and Pd electrodeposition at varying Pd concentrations is performed to obtain Ru-Mo-Pd/CNT catalysts. Ru-Mo-Pd/CNT catalyst is characterized by TEM and SEM-EDX. Characterization results reveal that Ru-Mo-Pd/CNT catalyst is succesfully synthesized. For electrochemical measurements ...More
