Incorporação de líquidos iônicos e nanopartículas metálicas na construção de sensores eletroquímicos

The most relevant advances on analytical applications of ionic liquids (IL) as binder in the construction of electrochemical sensors and biosensors based on carbon paste are presented. This new class of solvents - the IL - has received great attention in electroanalytical researches due to the excellent physical and chemical properties of these materials, such as high conductivity, low toxicity, good stability, large electrochemical window and catalytic ability. Recently, the interest in electrodes modified with IL, especially when combined with metallic nanoparticles, has increased expressively due to improve the sensitivity and others advantages discussed in this review.
