This special issue of Advances in Analytical Chemistry is focused on developments in both the application and theory of electroanalytical chemistry. Electroanalytical chemistry provides a sensitive, selective and easy approach to the detection and monitoring of many important chemical species. This issue demonstrates some of the wide range of applications where modern electroanalytical techniques have been successful applied in different areas including environmental monitoring, drug, biomedical and health analysis, offering advantages in sensitivity, economics and the possibility for miniaturization. The coupling of electrochemical transducers with biological components has allowed for the development of the highly commercially successful glucose biosensor. Notable developments in improving the selectivity of this biosensor are shown utilising advances in polymer and nanotechnology. Both applied and theoretical issues are reported for real world problems in medical and environmental disciplines. The application and theory of advanced waveforms such as square wave and differential pulse voltammetry are explored. Such advanced waveforms have been shown to be some of the most sensitive analytical techniques available and have been employed for the determination of metal ions by anodic stripping voltammetry. Non- invasive methods based on potentiometric analysis are shown for monitoring oxidative stress are show and both theoretically and with an analytical application.

I would like to thank all the authors who contributed to this issue and also to the referees who have given freely of their time to make this possible.
