The Materials Research Society Symposium B, 'Multifunctional Polymeric and Hybrid Materials', was held November 30-December 5 at the 2014 MRS Fall Meeting in Boston, Massachusetts. This symposium proceedings volume includes recent advances in the process of achieving multifunctionality of materials by mimicry of biological structure and interactions, by the presence of natural or biologically active components, such as enzymes or polymeric prodrugs, via complex, but controlled physical behavior, e.g., actively moving polymers (shape-memory, shape-morphing), or by simultaneously performing...
