Although malaria is the most threatening parasitic disease worldwide and a global health issue, the current standard for its detection still remains the microscopic observation of stained blood smears. A novel cost-effective, automated, yet sensitive diagnostic method is needed for malaria detection both as an in-field instrument and as a laboratory tool for malaria researchers.

Our group aims to design such a device based on the detection of the magnetically induced linear dichroism of the malaria pigment crystals (hemozoin) by replacing the conventional polarization-modulation detection scheme with a rotating magnetic field. This concept enables a very high sensitivity detection of both synthetic and natural malaria pigment crystals as tested on suspensions of synthetic hemozoin; on hemozoin produced by in vitro Plasmodium falciparum cultures and on in vivo mouse models and human samples.

My brief introduction into the technological background will be followed by the presentations of the test results by my colleagues.
