An artificial nose helps neurosurgeons to identify cancerous tissue during surgery and enables the more precise excision of tumours. Electrosurgical resection using devices such as an electric knife or diathermy blade is currently a widely used technique in neurosurgery.

In the method developed by researchers at Tampere University, the surgical smoke is fed into a new type of measuring system that can identify malignant tissue and distinguish it from healthy tissue. An article on using surgical smoke to…
