 Research has been conducted primarily on the effects of radioactive radiation on humans and possible medical use, as well as on aerosols.After the Second World War, the institute was reopened in 1948 as the "Max Planck Institute of Biophysics".With the retirement of Boris Rajewsky in 1966 and the appointment of Reinhard Schlögl in 1965, the research work was oriented away from work with radioactive radiation towards the investigation of "mass transport through biological and artificial membranes".
