Electrochemical biosensor for the study of DNA methylation
Petrula, Jakub ; Hrdý, Radim (referee) ; Hynek, David (advisor)
This bachelor’s thesis deals with design and optimalisation of custom biosensor for detection of methylated DNA. Teoretical part explains the mechanism and importance of DNA methylation. Next section describes analytical methods used in connection with DNA methylation and some basic direct and indirect methods of detection. Final part is dedicated to experiment itself, which is divided into several sections. Section one deals witch modification of working electrode and optimalisation of detection method. Second section introduces two different ways of DNA methylation detection. First is based on direct detection and second one on detection through the biosensor. Final part shows determination of methylcytosine from sample based on analysing characteristic attributes of signal and numeric algorithm based on curve fitting.

Software FLIM system in confocal microscopy
Petrula, Jakub ; Odstrčilík, Jan (referee) ; Čmiel, Vratislav (advisor)
This bachelor thesis deals with the FLIM system utilization in confocal microscopy. It describes basic concepts which are closely related to the topic, such as principles of fluorescence, fluorescent dyes and principles of both fluorescence and confocal microscopy. Practical part involves work with the confocal microscope and set of intensity images acquisition of both the animal and plant cells. Final product of pratical part is fluorescence lifetime image. The thesis also describes an algorithm for generating a pseudocolor frames and created user interface.
