Abstract A glassy carbon electrode modified with per‐6‐amino‐β‐cyclodextrin (β‐CDNH 2 ) and functionalized single‐walled nanotubes (SWCNT‐COOH) was elaborated. This structure investigated for the detection of dopamine acid (DA) in presence ascorbic (AA). The sensor behavior studied by cyclic voltammetry, square wave voltammetry electrochemical impedance spectroscopy. analysis results show that modification CD derivative improves sensitivity selectivity DA recognition; response further...
Abstract A K + ‐sensitive capacitive electrolyte‐membrane‐insulator‐semiconductor (EMIS) based on a novel dibromoaza[7]helicene ionophore has been developed. An ion‐sensitive membrane polyvinylchloride (PVC) doped with the was deposited Si 3 N 4 /SiO 2 /Si‐p/Cu‐Al transducer. The properties of ‐EMIS chemical sensor were investigated by electrochemical impedance spectroscopy (EIS). All developed devices upon being tested have shown good sensitivity and linearity responses within range 10 −6 M...
The adsorption of a metal ion to polycyclic aromatic molecule such as helicene is the object our study.
In this article, Tetraphenylporphyrin molecules were synthesized and used as biosensor for Magnesium ion. The metallization of porphyrin is a fundamental step which needs to be studied educated. fact, adsorption isotherms magnesium nitrate on coated onto Quartz crystal are achieved at four temperatures. Then, statistical physics treatment has been applied deduce new microscopic interpretations the experimental data. main contribution analytical deduct some physicochemical parameters related...
A chemically coated piezoelectric sensor has been used for the determination in liquid phase of adsorption isotherm potassium. thin film aza[7]helicene was attached to surface a gold electrode quartz crystal microbalance using spin coating method.Statistical physics formalism applied elucidate mechanism potassium onto by aza[7]helicene. The simulation results showed that monolayer occurs with number per site about 1 and energy is less than 30 kJ.mol−1, characteristic physical adsorption.The...
