Colloidosomes made of gold nanoparticles offer strong plasmonic coupling

If colloidal gold self-assembles into the form of larger vesicles, a three-dimensional state can be achieved that is called "black gold" because it absorbs almost the entire spectrum of visible light. How this novel intense plasmonic state can be established and what its characteristics and potential medical applications are is explored by Chinese scientists and reported in the journal Angewandte Chemie.
