ABSTRACT

Biosensors could be useful tools to compete with often tedious,

complex, and expensive standard methods. Conductometric enzyme

biosensors have important advantages as they do not need the use

of a reference electrode; they operate at low-amplitude alternating

voltages, thus preventing Faraday processes on electrodes; they are

insensitive to light; and they can be miniaturized and integrated

easily by using cheap standard thin-film technology. In this chapter

some examples of enzyme conductometric biosensors with their

advantages and disadvantages and perspectives of their application

for different human domains such as biomedicine, environmental

monitoring, agriculture, and biotechnology have been described and

summarized.
