Researchers Aljaž Kavčič, dr. Maja Garvas, Matevž Marinčič and doc. dr. Matjaž Humar from the F5 department and dr. Boris Majaron from the F7 department of the Jožef Stefan Institute have, in collaboration with researchers from Graz University, published a paper in Nature Communications entitled Deep tissue localization and sensing using optical microcavity probes. In the paper they presented a new method for imaging through scattering tissues, based on localization of whispering gallery mode microresonators with spectrally narrow emission that enables a decomposition of diffuse signal into contributions from individual microresonators. The developed method combines the ability of precise localization on cellular level with possibility of sensing various parameters such as temperature, pH and refractive index, which makes it a versatile and promising tool in the field of deep-tissue imaging. First author of the paper Aljaž Kavčič presented the results of this work in his master’s thesis, for which he was awarded »Prešernova nagrada« of University of Ljubljana.
