Study of fluorescence lifetime and spectral changes of nanoparticles in cell biology
Pelc, Pavel ; Janoušek, Oto (referee) ; Čmiel, Vratislav (advisor)
This work deals with the study of fluorescence lifetime and spectral changes of nanoparticles in cell biology. It describes the principle of fluorescence, fluorescence microscopy and laser confocal microscope Leica TCS SP8. The classic FLIM method, the Lambda Square mapping and the division of nanoparticles are introduced there. In the practical part, the created program for the evaluation of fluorescence lifetime and spectral changes is described. The program can show two-dimensional lambda maps, the fluorescence lifetime and spectral shift in the space area. In the final part of the thesis, an experiment with rhodamine nanoparticles is carried out and it is evaluated using the created program and then discussed.

Software FLIM system with pulse white light laser in confocal microscopy
Grund, Pavel ; Odstrčilík, Jan (referee) ; Čmiel, Vratislav (advisor)
The theoretical part of this master's thesis is focused on research of confocal microscopy and FLIM method. There are a principles and types of confocal microscopy and the use of broad-spectrum laser as a basic light source of these microscopes. It gives what the FLIM method and its use not only in cell biology. The practical part thesis includes the acquisition of three sets of fluorescence intensity images with use of applications tunable pulsed laser, function TimeGate and detection of hybrid detectors. For practical elaboration of this thesis is in the software Fiji created a plugin, which is the source code in the Java programming language. The types of plugins and their uses are described in the third chapter of the thesis. This plugin including the graphical user interface in the form of the dialog box, proceses the fluorescence intensity images and creates a graphical representation of data showing the fluorescence lifetime, so called pseudocolor map.
