[Actual modalities of separation by magnetic methods of active biological compounds, cells and pathogenic agents].

The paper presents an overview on magnetic techniques of bio-processing and some of their possible applications. These techniques are in fact direct, or more frequently, indirect magnetic means for separation of particulate substances. A brief presentation of direct and of the most important indirect methods (magnetic carrier and magnetic fluids technologies) is made. There are shown some of the possible applications of magnetic bio-processing in bio-technology and medicine: active biological compounds fixation, isolation and modification, cells and cells organelles separation, removal of xenobiotics, immuno-magnetic testing, pathogen microbes identification.
