Study & working visits
The goal of the visit was to perform experiments on human cells using novel microscopic technique: differential dynamic microscopy (DDM). The plan of the experiments contained quantification of movement of subcellular components in native HeLa cells and observation of changes of mobility during programmed cell death (apoptosis).
The purpose of the travel was to assess the perspectives for future collaboration with the Soft Living Matter Group run by prof. Clifford Brangwynne at the Princeton University. The group conducts cutting-edge research in the field of physicochemistry of soft matter in living systems.
During the working visit Marta Janczuk-Richter was conducting research in Bionanophotonic Systems Laboratory Group (BIOS) led by professor Hatice Altug in the Swiss Federal Institute of Technology Lausanne (EPFL) in Switzerland. The main goal of the visit was to become familiar with the preparation and measurements of plasmonic biosensors.
The purpose of the visit was twofold: for the new group members to learn the experimental setup and procedure of two-photon vision threshold measurement and to verify applicability of an existing product of Fluence, manufacturer of femtosecond fibre lasers, for this technique.
During the visit to Swiss Federal Institute of Technology in Lausanne (EPFL, Switzerland), Łukasz Richter carried out research in the Prof. Francesco Stellacci’s group. Main goals of the working visit were 1) to get familiar with techniques of synthetizing and analyzing gold nanoparticles and 2) to analyze the influence of these nanoparticles on bacteriophages (viruses that attack bacteria).
Professor Maciej Wojtkowski (the ERA Chair holder, the Head of the Department of Physical Chemistry of Biological Systems) accompanied by the:Director of the Institute of Physical Chemistry PAS - professor Marcin Opallo, President of the Scientific Council of IPC - professor Aleksander Jablonski Project Coordinator - professor Robert Holyst, and former postdoc at Professor Holyst Group – Associate Professor Hou Sen, linking person with Nankai University,
visited Nankai University in Tianjin, China (the 6 – 8th March, 2017).
Two-photon excitation fluorescence (TPEF) imaging of the back of the eye allows visualization of subcellular structures in the living animal eye. This method is helpful for investigating mechanisms of retinal diseases and development of ophthalmic therapies.
Working visit to Optical Biomedical Imaging Group Institute of Physics, Nicolaus Co-pernicus University.
The visit to Optical Biomedical Imaging Group Institute of Physics, Nicolaus Copernicus University was to have the deep analysis of the in-vivo imaging of the global mouse brain ischemia (GI) using Bessel beam optical coherence microscopy. This method allows to monitor changes in brain structure with extra control of blood flow during the process of artery occlusion.
The main goal of the visit was to present the research activity of the Physical Optics and Biophotonics Group to the researchers from Medical University Gdansk and University of Gdansk, get to know their scope of research and search for potential areas of cooperation and common research topics between both the institutions.
The purpose of this business trip was to perform collaborative work on the interferometric near-infrared spectroscopy (iNIRS). More specifically, experiments to quantify optical properties in dynamic media were performed. Then, the data was processed numerically using the new method of correlation gating to separate ballistic and scattered light transmitted through thick samples.
