Biospectroscopy and Bioimaging Laboratory

The Laboratory of Biospectroscopy and Bioimaging (LBB) contains advanced measurement instruments along with auxiliary optical, spectroscopic and photodetector components, which enables undertaking innovative and original research in a wide area of biospectroscopy and bioimaging.

In particular, the laboratory allows for:

  • designing new, unique, and personalised experiments in biospectroscopy and bioimaging domain based on a fully automated optical fluorescence microscope, programmable array microscope and other advanced laboratory equipment
  • designing, synthesis and bio-functionalization of lanthanide-doped luminescent nanoparticle labels, as well as their versatile spectroscopic characterisation, further optimisation and application in vitro

We are focused on luminescent nanoparticles’ chemistry and physics, light, spectroscopy and design of optical instrumentation to design novel luminescent materials and (bio)detection methods or instruments.


  • Cooperation with partners from academia and industry within fundamental as well as applied research projects
  • Designing, automation and testing specialized biodetection methods and building prototype instruments
  • Expert consultations in the areas of biospectroscopy, biodetection and bioimaging
  • Training courses in biospectroscopy, laser safety and applications of nanoluminophores

Artur Bednarkiewicz received his MSc Eng. in Physics and Biomedical Engineering from the Wroclaw University of Technology in Wroclaw, Poland, in 1993 and a PhD and habilitation in Physics from the Institute of Low Temperature and Structure Research, Polish Academy of Sciences, in 2003 and 2013 respectively. After 4 year lasting postdoctoral research in the European Commission Joint Research Centre, Italy, he returned to ILT&SR PAS in December 2008 and simultaneously established an interdisciplinary team NAOMIS with the Wroclaw Research Centre EIT+ focusing on Nanoparticle Assisted Molecular Imaging and Sensing (NAOMIS). His current interdisciplinary research focuses on optical (bio)spectroscopy, novel designs of lanthanide doped nanoparticles and quantum dot biolabels, optical and spatial light modulation engineering, as well as on pure physics, spectroscopy and chemistry of lanthanide doped materials. Since 2015 he is an associated professor at Institute of Low Temperature and Structure Research, PAS, Poland. He is a co-author of over 90 publications (h-index >18, cited>1050, sum IF>150), he is an author of 4 patents and 3 patents applications. In the course of his research he has received numerous prizes (stipends from Ministry of Education, FNP Starting grant, Brussels Eureca). He has a broad experience as researcher (3 research grants as PI), reviewer (over 60 reviews of scientific papers, over 30 reviews of national (FNP,NCN) and international (EU FET Open RIA, Australian, Belgian) grants, reviewers of 2 Ph.D. theses, scientific supervisor to 6 M.Sc. and 2 Ph.D. students, entrepreneur (co-owner of Nanovectors Ltd. Company). Since 2014, he is also a member of Young Academy of Science, where he is engaged in widening European participation of new EU member countries. He is also Polish representative and active participant and collaborator of COST CM1403 European Upconversion Network (STSM manager, Web designer).
