Ambient Ionization: A Dream for the Surgical Oncologist? [PDF]
Clinical Chemistry, 2016 One challenge for the cancer surgeon is to consistently distinguish tumor from healthy tissue and definitively remove the tumor with clean margins. The pathologist plays a key role in confirming the identity of the tissue removed, but it takes time to remove the sample, send it to the pathologist, and receive an expert analysis.
