Researchers have developed the 'iKnife', which sucks surgical smoke into a mass spectrometer to indicate whether the cut tissue is healthy.

Researchers have developed a surgical knife that can analyze the smoke made as it cuts tissue and determine whether cells are cancerous or healthy. The “iKnife” can read out results in 1-3 seconds, whereas it can take up to 30 minutes for a doctor to examine a tissue sample.

ScienceNOW reports that Hungarian chemist Zoltán Takáts discovered that the vapor containing ionized molecules could be analyzed by a mass spectrometer. His team at the Imperial College London have tested the “iKnife” in the operating room.
