Abstract:
There are important physical fields, intrinsic to soft matter, which we can exploit to direct colloidal assembly. The central idea is this: When a colloid is placed in a soft host, the colloid deforms the host, with some energetic consequence. The host can be a fluid interface, a nematic liquid crystal, or a lipid bilayer membrane. In each of these examples, molding the soft matter host defines energy fields that drive colloidal assembly. In the small deformation limit, important analogies to charge multipoles guide our thinking. The value and limitations of these analogies are explored as strategies are developed for directed assembly.
