Electrochemical Detection of Structurally Different Aminoacids by Thin Layers of Undoped and Doped ZnO.

Popis výsledku v původním jazyce

Thin layers of undoped and doped ZnO were prepared by a sol-gel method using the dip-coating technique. The doped layers contained 10 mol. % of Li or 10 mol. % of Na. The films were yielded with thicknesses ranging from 140 nm to 160 nm. The layers were analyzed by SEM, EDX, XRD, Raman spectroscopy, and by electrochemical tests (amperometry, linear voltammetry, and open circuit potential). All prepared samples were smooth and transparent. A series of electrochemical measurement was performed with both doped and undoped layers with aminoacids solutions of electrolyte. The glycine, glutamic acid, histidine, and methionine were chosen. Glycine possesses alkane chain, glutamic acid the second carboxylic group, histidine the alkalic amino group, and methionine the sulphur containing group. It was shown, that the change in polarity of ZnO induced by doping with 10 mol. %. Na and 10 mol. %. Li played an important role in surface interaction of ZnO and aminoacid dissolved in the electrolyte and permitted the qualitative and semi-quantitative distinguishing of the four structurally different aminoacids.nn
