Abstract:
Proteins are well-known to form crystals and show promise as templates for making nanoparticles. We exploit these properties to create 3-dimensional protein-based nanoparticle arrays. In previous studies a magnetic protein, magnetoferritin, was formed by replacing the core of the natural iron storage protein molecule ferritin with a ferrimagnetic oxide. Here the crystallization of magnetoferritin to produce large, regular, 3-dimensional arrays of synthetic nano-magnets is demonstrated. Interactions within the arrays strongly influence their magnetic properties.
