Abstract
A method of separating a mixture of discrete structures dispersed in a fluid material includes identifying a target structure and a non-target structure; providing a custom-shaped particle having at least a portion of a surface that is substantially shape-complementary to a portion of a surface of the target structure; introducing the custom-shaped particle into the fluid material; exciting reconfigurations of the custom-shaped particle with respect to the target structure and the non-target structure; binding the custom-shaped particle to the target structure through an attractive interaction to form an aggregate; and isolating the aggregate containing the target structure and the custom-shaped particle from the non-target structure. The custom-shaped particle preferentially binds with the target structure without binding with the non-target structure.
