Katarina and Sune Svanberg: Biophotonics applications of gas in scattering media absorption spectroscopy (GASMAS)

In this BiOs Hot Topics session, Katarina and Sune Svanberg of Lund University and South China Normal University discuss biophotonic applications of GASMAS (gas in scattering media absorption spectroscopy), an optical technique for sensing and analysis of gas located within porous and highly scattering solids that was introduced by Sune Svanberg in 2001.

Among the applications they discuss are food monitoring for safety and freshness based on non-intrusive measurement of oxygen levels; and medical diagnostics, such as monitoring tissue degradation following hip replacements, oxygen levels in neonatal and premature infants, and diagnosing ear infections via the gas signals that occur behind the ear drum.

Katarina Svanberg is a professor and chief consultant of oncology at Lund University Hospital (Sweden) and also active at South China Normal University. Her contributions to the fields of tissue spectroscopy and photodynamic therapy have brought her recognition throughout the world, and her research collaborations cover five continents. Her groundbreaking work on laser-induced tissue fluorescence have made "optical biopsy" a reality for many types of cancer.

Sune Svanberg is a senior professor of physics at Lund University and former director of the Lund Laser Center. He is the co-author of more than 600 scientific papers, with more than 30 patents and patent applications. He is a member of the Royal Academy of Sciences, and was a member of its Nobel Committee for Physics for 10 years, including two years as chairman.
