| abstract |
The present invention generally provides compositions comprising particles having various sizes and shapes, as well as methods for production of such particles. Particles of the invention may comprise complex, multi-valent structures. In some cases, the particles may have at least one concave surface. The present invention may advantageously provide facile, high yielding methods for producing complex particle structures. The particles may exhibit novel optical or mechanical properties, making them useful as photonic crystals, phononic crystals, mictrotrusses and microframes, multivalent colloidal particles, delivery agents, or the like. |
