The dissertation thesis deals with the biophysical interpretation of quantitative phase imaging (QPI – Quantitative Phase Imaging) obtained using coherence-controlled holographic microscopy (CCHM – Coherence-Controlled Holographic Microscopy) in the Q-PHASE microscope, Telight, Brno). The theoretical part of this thesis deals with the characteristics of quantitative phase imaging, which provides non-invasive information on the activity of living cells in vitro. The main part of the work consists in elaborating a concept and verifying it of a new methodology (PAMP – Primary Assessment of Migrastatic Potential) for the first critical evaluation of drugs for expected anti-migratory/metastatic potential. The result of this method is considered the first sorting evaluation when considering specific migrastatic agents for future complex oncological treatment. PAMP evaluates the speed of cell migration, the growth of tumor cells and controls the risk of appearance of invasive phenotypes. Furthermore, the correlation microscopy method between the Q-PHASE microscope and the laser scanning confocal microscope (LSCM) is proposed to evaluate cell behavior and the occurrence of focal adhesions after drug application. The quantitative phase image obtained using the Q-PHASE microscope is compared with the quantitative phase image from the HoloMonitor (PHI AB, Sweden), on which the PAMP method has been positively verified.
