Digital image processing and chemical microscopy:
-) Use of ImageJ for quantification of fluorescence intensities and particle counting
-) Deconvolution (using Huygens)
-) Raman microscopy

Inhaltliche Voraussetzungen (erwartete Kenntnisse)

Basic knowledge of cell biology is strongly recommended! This course is specifically recommended for PhD-students.

Lehrziel

Students will know the basic principles and applications of microscopy in life sciences and will have increasing confidence in handling basic light and fluorescent microscopes. They will be able to select the appropriate microscope and design an experiment including the proper controls for their individual application. Furthermore, students will be able to identify important aspects of the different techniques, critically interpret results and perform basic troubleshooting. They will understand the basic principles and applications of more advanced microscopical techniques and thereby have the confidence to gain a deeper understanding by consulting the relevant literature on their own.
