dc.description.abstractDetecting organic and inorganic contaminants is one of the most important environmental concerns today. Consequently, the search for low-cost materials and efficient technologies for solving such a problem has increased, becoming of the utmost importance.Within this context, the present study applied a new nanostructured bioinorganic hybrid material with great potential in the field of nanotechnology: yeast Saccharomyces cerevisiae chemically modified with cubic silsesquioxane. Based on voltammetric measurements with modified graphite paste electrodes with yeast/silsesquioxane and methylene blue (YSB), the value of anodic peak current decreased linearly as the concentration of sulphite increased. The limit of detection obtained was of 0.60 μmol L−1 and sensitivity amperometric (Sa) of 5.8 × 10−4 μA/mol L−1en
