Abstract
The paper presents the evaluation of photodynamic therapy (PDT) procedures with an application of a microsystem. Two cell lines were used in the experiments, i.e. human lung carcinoma - A549 and normal human fetal lung fibroblast MRC5. Mono-, coculture and mixed cultures were performed in a microsystem at the same time. The microsystem consisted of a concentration gradient generator (CGG) which generates different concentrations of a photosensitizer, and a set of microchambers for cells. The microchambers were linked by microchannels of various length in order to allow cells migration and in this way cocultures were created. Transparent materials were used for the chip manufacture, i.e. glass and poly(dimethylsiloxane). A high power LED was used to test photodynamic therapy effectiveness in the microsystem.
