Silk‐on‐Silk Layer‐by‐Layer Microcapsules

Single-component silk-on-silk microcapsules based on a layer-by-layer approach demonstrate the fabrication of highly permeable microcapsules with controlled permeability, porosity, and shell thickness. The formation of monodisperse robust capsules is afforded as a result of the formation of a β-sheet-rich structure of the absorbed silk proteins and hydrophobic–hydrophobic interactions.
