A eletrossíntese e o desempenho eletroanalítico do compósito poli-L-metionina -nano Au foram descritos matematicamente, sendo a primeira descrita etapa por etapa. Os modelos matemáticos foram analisados por meio da teoria de estabilidade linear e da análise de bifurcações. A partir da análise foram inferidas as condições do estado estacionário estável (do modo mais confortável para a eletropolimerização, e do melhor desempenho do sensor), bem como das instabilidades oscilatória e monotônica. As conclusões da modelagem vão ao encontro do observado experimentalmente, completando também o conhecimento do processo
The electrosynthesis and the electroanalytic function of the poly-L-methioninenano-Au composite were mathematically described and the first one of the processes was described stage by stage. The mathematical models were analyzed by linear stability theory and bifurcation analysis. Basing on the analysis, the stable steady-state conditions, like also oscillatory and monotonic instability conditions were inferred.
