The pen releases a drop of water onto the tissue and small molecules migrate into the water, which enables the device to drive the water sample into an instrument called a mass spectrometer to detect thousands of molecules as a molecular fingerprint. "But our technology could vastly improve the odds leading surgeons to really remove every last trace of cancer during surgery", Eberlin added.
It produces a chemical fingerprint that tells doctors whether they are looking at healthy tissue or cancer. The spectrometer searches for compounds that make lung, breast and other types of cancer cells different from healthy ones using algorithms to search a database.
The team tested their pen on more than 250 samples of human tumors, calibrating the molecular signature of each type of tumor.
When tested on 253 tissue samples from healthy patients and patients with cancer, the device took around 10 seconds to identify cancerous tissue, and it yielded 96.3 percent accuracy, 96.2 percent specificity, and 96.4 percent sensitivity. The team is now working on pens that can analyze smaller sections of tissue. It uses tiny water droplets to analyze human tissue samples for cancer and is 96% accurate, the inventors explained in a statement. That is 150 times faster than existing technology.
Frozen Section Analysis is now the preferred method for diagnosing cancers and determining the boundary between cancer and normal tissue during surgery.

The release notes "staff and students should plan to report back to school on Wednesday, Sept. 13, 2017 unless othewise notified". The Florida Maritime Museum (FMM) will be closed to the public on Friday, Sept. 8 and Saturday Sept. 9. St.
A handheld device that looks like a pen can identify cancerous tissue within 10 seconds, according to scientists at the University of Texas.
An experimental pen-like probe can make surgery to remove tumor quicker, safer, and more precise.
Researchers said that the device will require more testing before it can be validated. "The differing chemistry of a cancerous cell and normal brain tissue means the laser help surgeons find the outside edge of a tumour", says a BBC report.
Additionally, the MasSpec Pen was found to accurately detect cancer in live mouse models, without causing any damage to healthy tissue. "It allows us to be much more precise in what tissue we remove and what we leave behind".
"If you talk to cancer patients after surgery, one of the 1st things many will say is 'I hope the surgeon got all the cancer out". The UT team expects that the MasSpec Pen will be used in oncological surgeries starting in 2018.
