Tematika

Microchip capillary electrophoresis is an interesting approach for an increasing number of analytical problems in environmental applications and health science. The determination of size, quality and concentration of biomolecules such as DNA, RNA and proteins is one of the fundamental steps in life science research. Traditional methods for this type of analysis, such as gel electrophoresis or capillary electrophoresis, can now be complemented by an analytical technique, Lab-on-a-Chip technology. This technology enables downscaling and integration of several experimental steps (injection, labeling, dilution, separation, detection) into one process, in combination with automated data analysis. Lab-on-a-Chip technology has several advantages compared with conventional techniques, such as minimal sample requirement, rapid analysis times, ease-of-use, minimized exposure to hazardous materials and reduced waste generation.

The course deals with the theoretical background and application of the microfluidic methods, such as electrophoresis for detection of proteins, endotoxins, DNA, RNA and flow cytometry for detection of cells (bacteria, fungi, cancer cells, etc.).
