FIG. 13.2 Representative images of cochlear neural explants grown on polypyrrole/sodium salt polymers with and without neurotrophin. Neur-
ites were visualized by immunocytochemistry with a neurofilament-200 primary antibody and a fluorescent secondary antibody (green). Cell nuclei
are labeled with DAPI (blue). (Reproduced with permission from R. Ravichandran, S. Sundarrajan, J.R. Venugopal, S. Mukherjee, S. Ramakrishna, Applica-

ultimately induce cellular growth or death, and the possibility of entering the body and reach spaces that are inac-
cessible by other materials [119, 120] are just few examples of the important properties these materials hold. More-
over, at sizes below 20nm, magnetic nanoparticles exhibit superparamagnetic behavior, and no remanent
magnetization is observed when the magnetic field is removed, making them suitable for in vivo applications since
it prevents aggregation and enables to easily redisperse rapidly after withdrawing the magnetic field [119]. Besides
the nanoparticles the use of magnetic liposomes has been increasingly investigated in the field of biomedicine due
