An illustration showing the approach for assembling biologically functional proteins into ordered 2D and 3D arrays through programmable octahedral-shaped DNA frameworks. These frameworks can host and control the placement of the proteins internally for example, at the center (1) or off-center (2) and be encoded with specific sequences externally (color coding scheme) to create desired 2-D and 3-D lattices. For example, red only connects to red, blue to blue, and so on. The team demonstrated the preserved biological activity of ferritin lattices by adding a compound (ascorbate) that induced the release of iron irons forming the ferritin core. ....
