Study & working visits
Michał Hamkało as a member of the prof. Wojtkowski team took part in a working visit at the Max Planck Institute. The bussines trip was organized in order to perform the first 3D OCT measurements of a beating rabbit hearts (in Langedorrff perfusion system). All measurements were done together by the team of prof. Wojtkowski and their collaborators from Max Planck Institute for Dynamics and Selforganization (dr Jan Christoph, Stephan Luther) in Goettingen and from Institute for Biomedical Optics in Luebeck (T. Pfeiffer, W. Draxonger and prof. Huber).
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. An extra target was to explore requirements of the method and setup to start the process of adapting the Fluence laser when it comes to integration into the measurement device.
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).
Together with other members of the group Jan Guzowski visited Prof. Roland Zengerle Lab at University of Freiburg, Germany. The agenda of the meeting included presentation by Prof. Zengerle as well as by other two group leaders in his lab, namely Dr. Peter Koltay and Dr. Felix von Stetten. The purpose of the visit was to establish long-term collaboration with prof. Garstecki lab, in particular associated with co-advising by prof. Zengerle of two PhD students, Yu-Ting Kao and Yu-Kai Lai.
Yuriy Stepanenko visited the University of Nevada, Reno. The purpose of this study visit was to continue the collaboration began in 2007 with the group of Laser-plasma interaction at Nevada Terawatt Facility, University of Nevada, Reno. The group uses advanced laser sources for plasma generation, particle acceleration and diagnostics of Z-pinch.
This visit was scheduled in cooperation with one of the best group in the field of ultrafast Optical Coherence Tomography (OCT) – prof. Huber group from Lubeck. The purpose of the visit was to obtain results from ultrafast (up to 100 vol./s) OCT on rabbit and mice hearts. In order to do that, we have made a cooperation with Max Planck for Dynamics and Self-Organization from Goettingen, which gave us a support from biological point of view (also provided with well-prepared hearts).
The goal of the visit was to carry first in the world investigation of full heart with use of OCT system. For that Michał Hamkało had to get newly extracted hearts of mice from an authorized laboratory in Goettingen and took it to Luebeck (to next cooperator) with help of dr Jan Christoph. In the Institute for Biomedical Optics in Luebeck he was working with the OCT system (one of the fastest in the world) in order to specify parameters of heart imaging.
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. The group possesses a wide background and know-how concerning biophysical studies on model biological systems at all complexity levels (single cells, tissues and organisms). It is applied there, i.e., to studies of phase transitions in living systems and intrinsically disordered proteins, which play a key role in the pathogenesis of neurodegenerative diseases.
