“…Analytical performance of PDA-β-CD-GCE has been compared with other reported electrodes and the results are shown in Table 1 [27][28][29][30][31][32][33][34][35][36][37][38]. Binuclear manganese (II) complex modi ied CPE requires 60.0 s accumulation times prior to the determination of Trp and moreover, the energy required to oxidize Trp at this electrode was more as compared to PDA-β-CD-GCE [28].…”

“…Ag@C core-shell nanocomposites preparation was tedious and it required an electrochemical pre-treatment of glassy carbon electrode prior to the preparation of Ag@C/GCE [35]. The oxidation overpotential at expensive BDD NWs [36] was very high and it required a highly basic medium for the electrocatalytic oxidation of Trp. A two-step procedure was involved in the preparation of GNP/ CILE [37].…”

The main purpose of this report was to develop application of poly-dopamine-beta-cyclodextrin modifi ed glassy carbon electrode (PDA-β-CD-GCE) towards electrooxidation and determination of L-Tryptophan (L-Trp) and also the evaluation its kinetic parameters. In continuation of our efforts to use PDA-β-CD-GCE for amino acids detection, our objective in the present work was to expand application of this sensor for the determination of L-Trp which is very sensitive.

“…Similar to the electrochemical responses of different biological molecules at other electrodes, cvp2-cvp2′ produced from the CV of tartaric acid at the Cu vanadate nanorods modified GCE is also considered to be the adsorption-desorption process between tartaric acid and tartrate. The electrochemical responses of biological molecules at the electrodes have been affected by the scan rate (Szunerits et al, 2010;Davis et al, 2000). The CVs of tartaric acid with the concentration of 2 mM in 0.1 M KCl solution at the Cu vanadate nanorods modified GCE are shown in .…”

Cu vanadate nanorods have been used as the glassy carbon electrode (GCE) modified materials for the electrochemical detection of tartaric acid. The effects of scan rate, tartaric acid concentration and electrolytes in the electrochemical behaviours of tartaric acid in KCl solution have been analysed. Two pairs of semi-reversible cyclic voltammogram (CV) peaks are observed. The CV peaks are located at +0.12 V, -0.04 V (cvp1, cvp2) and -0.07 V, -0.41 V (cvp1′, cvp2′), respectively. The intensity of the electrochemical CV peaks increases linearly with the increase of the scan rate from 25 to 200 mVs -1 , tartaric acid concentration from 0.01 to 2 mM, respectively. The detection limit is 7.6 μM and 1.3 μM for cvp1 and cvp2, respectively at a signal-to-noise ratio of 3. Cu vanadate nanorods modified GCE shows good stability.Keywords: tartaric acid; Cu vanadate nanorods; electrochemical detection; glassy carbon electrode; GCE.Reference to this paper should be made as follows: Pei, L.Z., Wei, T., Lin, N.

Nanodrähte aus sp3‐C‐C‐gebundenem Diamant sind Halbleiter mit einer breiten Bandlücke und einer Kombination ausgezeichneter Eigenschaften wie einer negativen Elektronenaffinität, chemischer Inertheit, einem hohen Elastizitätsmodul, höchster Härte und höchster thermischer Leitfähigkeit bei Raumtemperatur. Über die Herstellung von 1D‐Diamant‐Nanodrähten können die zentralen Eigenschaften von Diamant durch Erhöhen des Verhältnisses von Oberfläche zu Volumen gesteuert und verbessert werden. Der theoretische Vergleich mit Kohlenstoff‐Nanoröhrchen zeigt, dass Diamant‐Nanodrähte energetisch und mechanisch existenzfähige Strukturen sind – die reproduzierbare Synthese kristalliner Diamant‐Nanodrähte bleibt aber schwierig. Wir geben eine aktuelle und umfassende Übersicht über Diamant‐Nanodrähte, in der wir ihre Synthese, Strukturen, Eigenschaften und Anwendungen diskutieren.
