Mushroom-shaped objects

Figure 6.3 The chemical compositions for macromolecular objects that result from crosslinking within nanodomains of bulk phase separated block copolymers include (a) core-crosslinked spheres (b) core-crosslinked rods (c) mushroom -shaped objects.

FIGURE 8.14. (A) A schematic illustration of the setup used to project an F-shaped object onto the focal plane through an array of microlenses. (B, C) images formed at the focal plane of an array of mushroom-shaped (B) and hemispherical (C) microlenses. The microlenses used in all of these demonstrations were fabricated by templating 5.7- tm polystyrene beads against 2D arrays of cylindrical holes that were 5 pm in height and diameter. 

One of the major motivations for the study of nano-aggregate formation, either in bulk or in solution, is because it provides an opportunity to construct macromolecular objects with dimensions significantly larger than molecular dimensions, and therefore would pave the way to further organize them well into the macroscopic domain. Thus, this serves as a step-wise approach to organizing macromolecules in the bulk phase, with a control over the molecular organization at each step along the way. The fixation of the mushroom-shaped supramolecular ag-...
