Tools for Assembly: Bioinspiration in Materials Science

Tools for Assembly
Reported by

Posted January 11, 2008

Overview

At the first meeting of the Academy's Soft Materials Discussion Group on November 7, 2007, two speakers discussed how biology can inspire strategies for making minerals or even synthesizing whole libraries of self-assembling molecules. After describing the versatility of biological assembly in the sea sponge, Joanna Aizenberg explained how her team uses this knowledge to create arrays of crystals in precise structures and locations. Virgil Percec described how he and his colleagues systematically catalogued structures formed in a library of organic molecules, and then used these structures to guide their synthesis of new compounds.
