Description of Research
Research in my laboratory is focused on the development and applications of probes for medical imaging. Specifically, the lab is developing advanced paramagnetic probes that enable in vivo measurement of physiologically relevant parameters, such as enzyme activities, oxygen concentration or pH non-invasively using magnetic resonance based techniques (EPR/NMR). The development of nanoparticles loaded with an imaging probe and/or a therapeutic agent for diagnostic and/or therapeutic purpose is also an important part of our work. The laboratory develop fluorescence probes that allows for in vivo imaging of reactive oxygen species (ROS). Finaly, we desing and synthesize polarizing agents that allow to enhance the sensititivy of NMR and MRI techniques.
