Self-cleaning sensors see the light

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.

Infrared offers odds on skin cancer spreading

Scientists in Belgium have shown that infrared spectrometry can help predict how likely it is that a melanoma tumour, the deadliest and most common form of skin cancer, has spread to other organs.

Tumour spread, or metastasis, is the main threat to survival in melanoma patients. However, no biomarkers have been identified to indicate a high risk of metastasis and visual assessment of primary tumours by a trained pathologist is unlikely to reveal if cancerous cells have escaped to other parts of the body.
