title: Amyloid Templated Gold Aerogels.
abstract: Amyloid fibril-based ultralow-density aerogels are designed by functionalization with gold nanoparticles and microcrystals, leading to hybrids of unprecedented lightness and functionality. By changing the colloidal gold shape, size, and concentration, the gold composition can be tuned to reach contents ≥20 kt equivalent, yet at densities ≈10(3) lighter than any equivalent gold alloys, and combining unique features such as porosity, catalytic properties, pressure sensing, and autofluorescence.
