摘要：
Healing hands: A complex interplay between colloidal and polymeric energetics in microgel selfassembly behavior results in soft colloidal assemblies with self-healing properties. Repulsive soft spheres can adopt highly compressed conformations in colloidal crystalline lattices without directly contacting the nearest neighbors (see picture). This distant action is directly responsible for the self-healing of the assemblies. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
