title: Nanopatterning of Magnetic CrNi Prussian Blue Nanoparticles Using a Bacterial S-Layer as a Biotemplate.
abstract: We have developed a simple process to fabricate on a bioplatform patterns of nanoparticles of a molecule-based magnet. Nanoparticles of the ferromagnetic Prussian blue derivative CsxNi[Cr(CN)6] were orderly deposited onto S-layers of Lysinibacillus sphaericus, forming a dense carpet of nanoparticles following the square lattice (p4) pattern of the biotemplate. These results are encouraging to extend this approach by focusing on molecule-based magnets patterned into domains with controlled shapes and positions on a biosurface.
