Self-cleaning sensors see the light

Written by Simon Neil for Chemistry World

Graphical AbstractScientists in Italy have engineered a cheap and simple electrochemical sensor that cleans itself when exposed to ultraviolet light. Their system offers a route towards self-cleaning electrodes with myriad environmental and biomedical sensing applications – from detecting pollutants in water to monitoring medications in blood.

Open any book on chemical or biological sensors and you’ll find a lot of content on electrochemical devices. This prevalence is testament to the importance and advantages of electrode-based sensing; and electrodes containing nanomaterials are becoming increasingly popular, owing to their high surface-to-volume ratio, which can improve their sensitivity and lower costs.
