'CSI' Device Used in Real-World Healthcare

Thursday, 23 August 2012 09:55 AM

A futuristic scientific device featured on the TV shows CSI and CSI: Miami for instant fingerprint analysis has actually been found to be effectively used in a variety of real-world medical applications – including helping doctors deliver effective doses of chemotherapy to cancer patients and in brain surgery procedures.
A report detailing the many medical uses of the device – called a "desorption electrospray ionization" (DESI) – was presented this week by Harvard and Purdue University researchers at a meeting of the American Chemical Society.
The DESI instrument, about the size of a shoebox, can quickly identify chemical signatures of a variety of substances – including pesticides, explosives, microorganisms, biological markers for prostate cancer and melamine, a potentially toxic substance that showed up in infant formulas and pet food in 2008 and 2007.
Purdue scientist Graham Cooks said tests of the instrument in the operating room during brain cancer surgery found it to be nearly as effective as traditional analysis of tissue samples by pathologists. Tests of a second device, similar to DESI, found it can effectively monitor the levels of chemotherapy drugs in patients' blood in real time.
"With [both instruments], no sample preparation is needed, which reduces analysis time from as much as several hours per sample to just a few seconds," said Cooks. "Rapid results are critical when a surgeon is operating on a brain tumor or when chemotherapy patients are being treated with powerful drugs that must be administered at precise levels.
"DESI can analyze tissue samples and help determine the type of brain cancer, the stage and the concentration of tumor cells. It also can help surgeons identify the margins of the tumor to assure that they remove as much of the tumor as possible. These are early days, but the analysis looks promising."
Cooks' team is now testing to see whether the devices can provide comparable information to what pathologists can provide by looking at human tissues under a microscope and measure the levels of drugs of abuse or pharmaceuticals in urine or other body fluids.
