Biomarker detection using electrochemical method with microfluidic chip
Klepáčová, Ivana ; Svoboda, Ondřej (referee) ; Neužil, Pavel (advisor)
The thesis is focused on the development of the electrochemical system with microfluidic platform for the detection of multiple biomarkers. It analyses the use of biomarkers for the early diagnosis of cancer. The theoretical part contains basic information about voltammetric methods and microfluidic systems. The practical part provides solutions to the microfluidic chips, including the description of the used materials, designs, methodologies of preparation and conclusions from the testing of the manufactured microfluidic systems. The thesis describes the lock-in electrochemical system which measures the response of 4 electrochemical cells simultaneously. For the electrochemical system measurements, an electrochemical chip consisting of 64 electrochemical cells was used. The results of the analysis include the processing of the system tests and detected voltammetric curves of the Fe2+/Fe3+ solution and cysteine.

The fluorescent marking of glass microelectrodes for the patch clamp system
Klepáčová, Ivana ; Ronzhina, Marina (referee) ; Chmelíková, Larisa (advisor)
The paper deals with the issue of the fluorescent marking of glass microelectrodes for the patch clamp system. It analyses in more details the possibilities of creation of glass microelectrodes from the choice of appropriate glass type to the construction of a microelectrode, which can be used in practice in experimental measurements. Phases of creation process of glass microelectrodes document possibilities of the development of the given technique. The description of fluorescence phenomenon includes the classification and description of fluorophores. The paper contains a theoretical analysis of the given issues and presents it in its comprehensive form. The practical part of the thesis suggests the procedure of the external fluorescent marking of glass microelectrodes which can be used in the measurement by means of the patch clamp system. It is concerned with the testing of the established procedure and provides the evaluation of the possible application of the suggested procedure in practice.
