Coated magnetic nanoparticles for applications in analytical chemistry and catalysis
Magnetic nano-materials have recently attracted much attention since they may have potentially many new exciting applications in a wide range of areas. The research described in this thesis has particularly focused on design, synthesis, assembling, testing and characterisation of some novel magnetic...

Magnetic nano-materials have recently attracted much attention since they may have potentially many new exciting applications in a wide range of areas. The research described in this thesis has particularly focused on design, synthesis, assembling, testing and characterisation of some novel magnetic nano-materials for potential applications.
