Figure 4. Micromasonry by using multi-layered, lock-and-key and 100μm microgel sub-units assemblies.

Figure 4

Images correspond to different 5mm diameter tubes. A shows a tube composed of 100μm sub-units [Bar=1.5mm]. Because of the irregularity of the sub-units, the tube wall has a disordered appearance which can be observed in B [Bar=0.25mm]. C is a tube formed piece-by-piece by 1mm complementary sub-units [Bar=5mm]. The assembly of lock-and-key sub-units can be observed in D [Bar=1mm]. E is a phase/fluorescence superposition image of a tube composed of two layers of 500μm sub-units with Nile-red stained blocks being used for the outer layer [Bar=2.5mm]. F is a more detailed image of the walls, where the interface can be clearly observed [Bar=0.5mm].
