“…graphene/P 4 SAc, ZnO-rGO, MnO 2 /MWCNT, and MWCNT-COOH/Poly(TB)-based DA sensors. (30)(31)(32)(33) Although the DA sensor based on Cu x O/ERGO/Au (34) has an even wider linear range and a smaller LOD than those in the present work, oxygen gas must be introduced during the electrochemical deposition process for the fabrication of the Cu 2 O/CuO/ERGO nanocomposite, which makes the fabrication process inconvenient. Moreover, the stability of the DA sensor in the present work is higher.…”

A novel dopamine (DA) sensor based on a polymerized mediator (PEI-Fc) and sulfo-groupfunctionalized graphene oxide (PEI-Fc/SFGO) composite modified electrode was developed. The PEI-Fc/SFGO composite was formed by electrostatic interaction, in which ferrocene (Fc) groups served as an electron transfer mediator to improve the sensitivity. Scanning electron microscopy (SEM) was employed to characterize the surface morphology of the PEI-Fc/SFGO composite. Ultraviolet visible spectroscopy (UV-vis) and Fourier transform infrared (FTIR) spectroscopy were performed to characterize the PEI-Fc and SFGO, respectively. Cyclic voltammetry (CV) was employed to investigate the electrochemical behavior of the PEI-Fc/ SFGO composite modified electrode. Linear sweep voltammetry (LSV) was employed for the quantitative detection of DA. The as-prepared sensor realized a wide linear range of 0.5-100 μM with a low limit of detection (LOD) of 0.1 μM for the determination of DA. This work provides a simple surface modification technique and a potential electrode material for the detection of DA.

A novel perylene diimide (PDI-C 8 SAc) was used as a modifier for carbon felt electrode (CFE) and prepared modified electrode was applied for dopamine detection. Obtained electrochemical current was almost 15-fold higher compared to plain CFE. Also a cathodic shift in the peak potential was obtained indicating the electrocatalytic effect of the developed sensor. Under optimized experimental conditions, a linear range was observed between 1-100 μM with a limit of detection value of 0.084 μM (n = 3). The fabricated sensor was successfully utilized for the dopamine determination in dopamine based medicines.

“…Full factorial experimental design works in an experiment which has two or more factors. By taking the upper and lower limits of our factors, experimental design method provides set of experiment using all the possible combinations of our limits and optimizes the factors to their optimal conditions [30, 31].…”

A biofuel cell (BFC) was fabricated by combining multiwalled carbon nanotube ‐platinum‐gold (MWCNT−Pt−Au) hybrid nanomaterial, glucose oxidase (GOx) and benzoquinone included carbon felt electrode (CFE) bioanode with apple tissue included CFE biocathode. The working parameters of bioanode were optimized both experimentally and chemometrically. For the biocathode, apple, banana and pear tissues were tried and best power output was obtained with apple tissue. By combining MWCNT−Pt−Au/GOx/CFE bioanode with apple tissue based biocathode, single cell, double cell with membrane and with salt‐bridge BFCs were formed. The best power output with highest current density were obtained with single cell BFC.
