We use and develop several research methods typically used in the field of pharmacy for the needs of microplastics research. We use molecular modeling for molecular level studies of plastics, we develop extraction and sample preparation methods for plastic samples and create analytical methods for NMR and mass spectrometry. The membrane permeability is studied using, among others, the PAMPA-method. We do particle size analysis, microscoping and imaging. In toxicological research we examine, for example, cell viability and inflammation markers.
