Patchy particles

Patchy particles are micron- or nanoscale colloidal particles that are anisotropically patterned, either by modification of the particle surface chemistry ("enthalpic patches"),[1] through particle shape ("entropic patches"),[2] or both.[3] Patchy particles are used as a shorthand for modelling anisotropic colloids [1] and proteins [4] and for designing approaches to nanoparticle synthesis.[5] Patchy particles range in valency from two (Janus particles) or higher.[6]
