Micron-size sculpted structures are important for encapsulation and functionalization technologies and as building blocks for larger devices. Here, spherical capsules are created through the self-assembly of recombinant spider-silk at liquid interfaces and in solution. Due to the natural properties of the spider silk the capsules are mechanically strong and biocompatible. These capsules can be formed either in bulk or through microfabrication using microfluidic devices, which allow for the direct control of capsule size and shell thickness. Functionalization of the capsules can also be achieved using common biochemical techniques. Because of the silk's unique properties, this technique potentially offers a convenient approach to the formation of biologically-compatible, easily-functionalizable structures.
