Last March 4th, Mr. Jordi Andreu Segura defended his paper “Statistical Mechanics of Superparamagnetic Colloidal Dispersions Under Magnetic Fields”, which was submitted to obtain a PhD degree in Materials Science at the Universidad Autónoma de Barcelona.
Protein purification using magnetic particles is well established in life science R&D but has not reached commercial acceptance for larger scale applications in bioprocessing. Preparative scale purification of antibodies using magnetic beads is far more time efficient, however existing column chromatography methods are significantly cheaper. To be competitive, the main challenges that need to be addressed for magnetic separations are:
