From page 23...
... The focus of his recent research has been on understanding how nature assembles organic and inorganic biomaterials and the molecular design and assembly of hierarchically structured threedimensional devices. Robert Langer of the Massachusetts Institute of Technology provided a second technicalperspective.

From page 24...
... Recent research trends that will challenge materials designers include the development of implantable biosensors, artificial muscles, drug delivery hydrogels, wound dressings, sealants and adhesives, tissue augmentation and regeneration, immunoisolation devices, and specific surface chemistry modifications. Many of these trends will be pursued through the broad field of tissue engineering.

... Other biological inspirations include species with so called "electrocute" cell arrays capable of delivering electrical power in excess of a kilowatt for substantial periods, such as 80 seconds. The three-dimensional hierarchical structure of so many biologically produced materials has already inspired some novel polymeric MEMS applications using two-photon optical curing with resolutions of 0.2 microns laterally and 0.28 microns in depth.

... The Bioengineering Consortium initiated in 1997 is intended to support bioengineering partnerships performing design-directed research. The NIH-sponsored Biomaterials and Medical Implant Science Coordinating Cornrnittee met in early 2000 to discuss ways to improve implant performance.
