Conceived of by Robert A. Freitas, Jr., respirocytes, or artificial nanomedical erythrocytes, are intended to duplicate all of the important functions of the red blood cell and could serve as a universal blood substitute, preserve living tissue, eliminate "the bends," allow for new sports records, and provide treatment for anemia, choking, lung diseases, asphyxia, and other respiratory problems.

Nanomedicine - The Foresight Institute
Robert A. Freitas Jr. is currently writing Nanomedicine, the first book to comprehensively address the technical issues involved in the medical applications of molecular nanotechnology and medical nanodevice design. Nanomedicine will be published in three volumes. The book represents a preliminary attempt to explore the full range of nanomedical applications, along with some details of the required foundational technical competencies. An established biomedical book publisher, Landes Bioscience, has been signed to produce all three volumes. Nanomedicine, Volume I, was published in October 1999 and may be ordered directly either from the publisher or from The anticipated publication date for Volume II is October 2002.

Center for Biologic Nanotechnology
The Center for Biologic Nanotechnology takes its name from two inspirations. First, the work of the Center is aimed at applying nanotechnology to solving biological problems of medical interest. Second, the Center believes successful nanotechnolgies can be quickly realized by following the example of biology, which has built multiple types of nanodevices by scaling up molecular entities. The Center begins with molecular entities and scales them up to nanotechnologic size devices.

The Foresight Institute
Foresight Institute's goal is to guide emerging technologies to improve the human condition. Foresight focuses its efforts upon nanotechnology, the coming ability to build materials and products with atomic precision, and upon systems that will enhance knowledge exchange and critical discussion, thus improving public and private policy decisions.
