Description of the Organisations and PI

Institute of Low Temperature and Structural Research, PAS is a research institute of the Mathematics, Physics, Chemistry and Earth Sciences Division of Polish Academy of Sciences. Research interests include wide research of physicochemical structure of solid state and connection to physical, chemical and spectroscopic properties, especially in low temperatures. Institute’s specialty are investigations of magnetic 5f- and 4f-electron systems, superconductors, physics of phase transitions and molecular spectroscopy. The main tasks of the Institute are: conducting scientific research (mostly basic, pre-application studies); scientific training of researchers and specialists with qualifications connected with Institute’s interests and used research methods; cooperation with universities and colleges in teaching duties; smoothing the way of applying of the obtained results; supporting of the governmental units in metrological duties; and popularization of knowledge connected with Institute’s interests. Institute Scientific Council has rights to award PhD and PhD hab. Degrees in physics and chemistry.


EIT+ Wrocław Research Centre is the first research and technology organization in Poland that is entirely focused on the development of innovations, new technologies, and the research reflecting the needs of the modern industry. EIT+ has the most comprehensive research infrastructure in the entire East-Central Europe (totaling more than 23,000 sq. meters of area), which has been fitted with the state-of-the-art laboratory equipment. Hence, EIT+ is able to run research projects that remain interesting for the industry as well as to perform basic tests compliant with the global development trends. By employing a team of competent scientists, research project managers, technology brokers, intellectual property specialists, and commercialization specialists, the EIT+ remains capable of answering the needs of various companies, research groups, and the society.


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, habilitation and Institute professorship in Physics from the Institute of Low Temperature and Structure Research, Polish Academy of Sciences, in 1998, 2013 and 2015 respectively. After postdoctoral research in the European Commission Joint Research Centre, Italy, in December 2008 he returned to ILT&SR PAS and simultaneously established an interdisciplinary team NAOMIS with the Wroclaw Research Center EIT+ focusing on Nanoparticle Assisted Molecular Imaging and Sensing. 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.

Description and scientific profiles of the group

Advanced measurement devices along with auxiliary optical, spectroscopic and measurement devices enable us to undertake 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
  • synthesis, bio-functionalization, testing, analysis, and interpretation of spectroscopic properties of Stokes and anti-Stokes lanthanide-doped luminescent nano-sized labels and quantum dots

Research infrastructure

Fully automated inverse fluorescence microscope CarlZeiss AxioObserver equipped with ▪ dry objectives 10x, 20x, 40x and immersion objectives 40x, 63x (NA=1.43), ▪ ultrasensitive 1-Megapixel cameras (EMCCD) in dual-camera configuration that enable simultaneous image recording in the same area of the sample in 2 spectral ranges, ▪ standard 5 Mpix colour camera, ▪ capacity to record fluorescence spectra from under the microscope with ultrasensitive spectrograph, ▪ capacity to work in white light, phase contrast, and Nomarski interference contrast imaging modes, ▪ full automation, with the option to integrate the use of automated microscope into custom control and measurement applications (LabView), ▪ CO2 incubator + temperature control for long-term in vitro measurements. Further, the system offers:

  • capability to carry out imaging in up-conversion mode (980 nm excitation, emission in Vis range) or NIR mode (808 nm excitation, 840-1050 nm emission)
  • capability to provide dynamic, spatially controlled initiation of photochemical reactions (e.g. photosensitizers' activation, photolithography, etc.) using DMD technology (Digital Micro-mirror Device, Texas Instruments) integrated with the microscope. Available LED source of 375 nm wavelength and 1024x768 array allows for optical resolutions of around 10 μm.

  • Extensive selection of opto-mechanical components that enables building custom optical and measurement setups
  • A set of optical-fiber semiconductor and "free-running" CW, quasi-CW and pulsed lasers (including 980 nm CW 3W, 808 nm CW 2W, and picosecond lasers up to 40 MHz at 375 and 405 nm wavelength)
  • Tunable Ti-sapphire laser in 700-1000 nm and 350-500 nm spectral range, under 1064 nm and 532 nm pump (>100 mJ in 10 ns pulse)
