A new class of ultralight gold materials is produced by combining amyloid fibrils with nanoparticles, as described R. Mezzenga and co-workers on page 472. The content up to 20 karat equivalent allows the preservation optical properties traditional alloys, yet at densities thousands times lighter. By changing colloidal shape, size, concentration, composition material functionalities can be finely tuned, allowing catalysis pressure-sensing applications.
