Patchy particles

Patchy particles [1] are models designed to keep pace with the rapid advances in the field of colloids. It is now possible to synthesise or fabricate tiny particles that have a variety of shapes, composition etc. In order to simulate these structures, there is a corresponding growth in the number of idealised models being developed and studied. With a view to classifying these "patchy" models the idea of "anisotropy dimensions" has been put forward.

Taxonomy: anisotropy dimensions[edit]

Anisotropy dimensions is a classification scheme for patchy particles [2]. The eight attributes are as follows:

Surface coverage (A)[edit]
