The current process we use for determining the boundary between cancerous and healthy cells during surgery—frozen section procedure—has been around for over 100 years. Let that sink in. While we’re sure there have been vast improvements in optimizing the procedure in the past century, it still takes about 30 minutes to prepare and analyze a section. That’s a lot of extra time to stay under for surgery. Well researchers at The University of Texas at Austin decided they wanted to make that time faster—about 150 times faster. Their device, the MasSpec Pen, is reportedly able to make the analysis within 10 seconds, is more accurate than FSP, and allows for more precision during tissue removal. Nice work, Longhorns.
