A descrição teórica da detecção eletroanalítica do letrozol, assistida pelo compósito VO(OH)- polipirrol, obtido catodicamente.

The process of the electroanalytical determination of letrozol drug, assisted by the cathodically obtained VO(OH)-Polypyrrole, has been theoretically described. For both the composite synthesis and electroanalytical function a mathematical model has been suggested and analyzed by means of linear stability theory and bifurcation analysis. It was shown that, contrarily to the cathodic polypyrrole electrosynthesis, initiated by a compound in a solution, the resulting cathodic polypyrrole has more "centred" morphology, in the relation to the matrix active centers, doped by VO2 + cations. Nevertheless, either the synthesis of the composite, or its electroanalytical function with letrozole may be considered efficient. [ABSTRACT FROM AUTHOR]
