  • Residual fragments can remain after kidney stone extraction which may necessitate another intervention. Magnetic nanoparticles (MNP) can be applied due to their properties of being able to bind to residual fragments and to be extracted by an external magnetic field. Calcium oxalate crystals and magnetic nanoparticles have been synthesized

  • For the sedimentation analysis and the magnetic sedimentation experiments a LUMiReader (LUM GmbH
  • Germany) with a cuvette holder containing either a permanent magnet (400 mT at surface) or a reference.LUMiReader was used to measure the particle velocity
  • This study shows that calcium oxalate crystals can be magnetically separated with MNPs in even small magnetic fields below 100 mT. MNPs irreversibly bind to calcium oxalate and form magnetic agglomerates. These agglomerates can be manipulated magnetophoretically in magnetic fields and behave similar to the simulation. These findings and the high biocompatibility [5
