Highly ordered protein cage assemblies: A toolkit for new materials

Protein capsids are specialized and versatile natural macromolecules with exceptional properties. Their homogenous, spherical, rod‐like or toroidal geometry, and spatially directed functionalities make them intriguing building blocks for self‐assembled nanostructures. High degrees of functionality and modifiability allow for their assembly via non‐covalent interactions, such as electrostatic and coordination bonding, enabling controlled...
