University of Latvia

University of Latvia (UL, with its ~17,000 students, 13 faculties and more than 20 research institutes is one of the leading universities in the Baltic States. Research is carried out in over 50 research fields; each year the University researchers take part in the development of around 900 projects, participate in ~1000 international scientific conferences, publish ~700 research papers.

Institute of Atomic Physics and Spectroscopy (IAPS, at University of Latvia with its ~50 staff members (including 20 physics doctors and ~20 bachelor, master and doctoral students) performs internationally recognised fundamental and applied research in atomic physics, spectroscopy, photonics and related areas, including biophotonics. The Institute has been previously supported by EC framework programmes – e.g. as a centre of excellence of fundamental and applied research (5FP GROWTH programme, contract # GIMA-CT-2002-04063). In February 2012 a large scale FP7 project FOTONIKA-LV (grant agreement #REGPOT-CT-2011-285912–FOTONIKA, ~3.8 M€) was launched, and Riga Photonics Centre in frame of this project has been opened.

Biophotonics Laboratory ( is the largest at IAPS, it employs ~20 researchers and technical staff members. The laboratory develops advanced optical methods and devices for noninvasive real-time cardiovascular monitoring and in-vivo assessment of skin. Since 1997 new modalities of photoplethysmography (PPG) have been proposed and studied for detection/analysis of skin blood pulsations, including multi-channel PPG, bilateral PPG, multi-spectral PPG, wireless PPG and non-contact PPG. In parallel, skin optics and spectroscopy studies are performed, including contact diffuse reflectance spectrometry, non-contact multispectral imaging, skin chromophore mapping, autofluorescence photo-bleaching and skin photo-memory studies. Laboratory is strongly application-oriented; most of the developed methods are implemented in proof-of-concept prototype devices that pass validation in Riga hospitals and clinics. Several patent applications have been submitted/approved. Fruitful international collaboration has been established with colleagues at universities in neighbouring countries (Vilnius, Kaunas, Tallinn, Moscow, Linkoping, Lund, Oulu) as well as in UK (King’s College London), USA (Columbia University, NY) and Taiwan (National Taipei University).

Round Robin Experiment

Raman spectroscopy has already proved its effectiveness in many cases for medical diagnostics such as for cancer, cardiovascular diseases and infections. However, there are no standards in the different working groups, e.g. for sample preparation, implementation of the Raman experiments, spectra pre-treatment, data evaluation, etc.In a round robin experiment, the required groundwork will take place in order to define standardised Raman measurement methods, which will be fundamental for establishing Raman spectroscopy for clinical diagnostic procedures.

5th International Conference on Biophotonics

20 March 2017

Continuing the success of the previous meetings held in Sacramento, Ottawa, Jena, and Florence, the 5th conference will come to Perth, Western Australia, running over two full days, and back-to-back with the Science on the Swan medical research conference, which delegates are strongly encouraged to also attend, at discounted rates. [more]
