1. Desenvolvimento de um biossensor potenciométrico, à base de soja, para a determinação de uréia / Biossensor potencyometric; Enzymatic membrane; Soy grains
In this work, the objective in study was the development of a biossensor potencyometric for urea detection, starting from the extracted urease of soy grains. Initially, was made a chemometrics study, through a planning factorial 24, objectified to find great conditions for the extraction of the urease without its properties were affected. Starting from this

2. Effects SAM on enzyme immobilization procedures in the peroxidase based biosensor performance / Investigação dos efeitos dos procedimentos de imobilização em monocamadas auto-organizadas da enzima peroidase no desenvolvimento de um biossensor
In this work different immobilization procedures of HRP were investigated using as support mIatrices the self-assembled monolayers formed on gold electrodes, as well as the evaluation of the influence of these immobilization processes in the biosensor performance. For this, the used monolayers were prepared by thiols with different structures, carbon chains
