Summary proceedings (48 pages in OpenBook browsable, searchable format) of a recent workshop on structured nanomaterials held on June 20-21, 2001 in Washington, D.C. Topics addressed include:

* Synthesis and assembly of nanomaterial building blocks
* Characterization of nanomaterials
* Examples of structural nanomaterials currently in use
* Potential applications of nanomaterials
* Gaps in understanding of synthesis, assembly, chemical, and physical characterization and the need for an interdisciplinary approach
* Identification of the "showstoppers" -- major barriers to utilization of nanomaterials
