Raman Spectroscopy as a diagnostic tool in medicine

Lactose intolerance is widely spread among the population: Prof. Borysow will describe a low cost, portable instrument for a full non-invasive diagnosis.

Lactose intolerance is widely spread among the population. By various accounts between 60% and 70% of people in the world have deficiency of lactase (an enzyme needed to digest the lactose). Lactase deficiency varies widely among different ethnic and age groups. Nearly 20% of Black, Asian and Hispanic children younger than 5 years will develop some form of lactose intolerance. The typical symptoms are: diarrhea, pain in the abdomen, nausea and bloating. These symptoms can be particularly dangerous for newborn children. More than 4 millions children are born every year in United States alone. Nearly 200,000 of them are lactose intolerant. Some infants develop symptoms so severe that they are at the risk of dying if not quickly diagnosed.

I will describe a low cost, portable instrument, which will be suitable for full non-invasive diagnosis of the lactose intolerance condition in newborn children. The technique utilizes a unique, compact, non dispersive Raman spectrometer, built around a laser diode and atomic absorption filters. The diagnosis is based on the detection, in real time, of traces gases in the person's breath at levels of few parts per million. The same spectrometer can be used for diagnosis of ulcer and numerous other diseases, perhaps even cancer.

Professor Jacek Borysow received M.S. degree in Nuclear Physics from the University of Warsaw in Poland in 1977 and Ph.D. degree in Physics with specialization in Atomic and Molecular Physics from The University of Texas at Austin in 1986. Before coming to Michigan Tech University (MTU) in 1989, he was a Member of JILA at the University of Colorado and NIST in Boulder Colorado. Dr. Borysow is a faculty member in the Department of Physics at MTU and faculty adjunct in the Physics Department at The University of Texas at Austin. He is currently working in the field of experimental atomic and molecular laser spectroscopy with applications in medicine.
