The functionalization of spider silk fibers promises to produce high‐strength fibers with very interesting properties, for example, magnetism. A method is described to prepare hybrid spider silk materials by binding inorganic nanoparticles to the surface or near‐surface region of a silk fiber immersed in a colloidal sol. The Figure shows that a magnetite–silk fiber remains flexible (see also the cover).
