In vivo voltammetry--prospects for the next decade.

In vivo voltammetry has been in existence for more than ten years. The technique now benefits from smaller, more selective sensors-true 'chemical microelectrodes'. The scope of experimentation has widened dramatically both in vivo and in vitro as new applications are reported. The speed of measurements has increased giving high temporal and spatial resolution, approaching 'real time'. This article discusses the progress of the past decade and looks forward to the advances of the next ten years.
