Introduction to Microscopy

General description

This course overviews main modern microscopy techniques used in cell biology. It deals both the theoretical background of the different types of microscopy and with practical aspects of sample preparation, digital data processing and experiment design will be covered. The main objectives of the course are to provide the students with the knowledge necessary to start a practical training on modern fluorescence microscopes and to describe the problems that can be solved by different specific types of microscopy.
