Measurement of reactive chemical species

This chapter will focus on the measurement of one specific type of analyte that plays a significant role in biology but poses a major challenge for electroanalytical measurement. Reactive species can be protective and destructive to biological systems and therefore, monitoring the accurate concentration that they are present in is critical. However, such molecules have significantly short half-lives and are highly reactive as the name suggests. This chapter will explain the role these general molecules play in biological systems, how these reactive species are formed, and the challenges associated with measurement of these molecules. Following this, there will be some insight into the varying strategies utilized for monitoring these molecules with some examples of studies conducted.
