Submission + - Surgical Electro-Scalpel 'Sniffs Out' Tumors->

TechReviewAl writes: Researchers in Germany have developed a surgical tool that uses chemical analysis to identify cancerous tissue as a surgeon cuts. The instrument uses a modified mass spectrometer--a device that uses ionized molecules to perform very accurate chemical analysis--to pinpoint tumors so that surgeons can make sure they remove everything. Mass spectrometry has been used to study biopsied biological samples before, but never used in-situ. The key was to harness ionized gas already produced by the electro-scalpel.
