nano is greatnecessary for the assembly of nanoscale electronic devices. These biological materials conduct current, transfer molecules from one location to another, are capable of major color changes on application of current or light and can produce cascades that can be used for amplification of a optical or electronic signal. All of these properties can be applied to electronic switches, gates, storage devices, biosensors and biological transistors to name just a few. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 1. The applicability of manufacturing at an ever smaller scale is nowhere more self-evident than in computer technology. Indeed, Moore's law [Moore 75] (an observation not a physical law) says that computer chip feature size decreases exponentially with time, a trend that predicts atomically precise computers by about 2010-2015. This capability is being approached from many directions. Here we will concentrate on those under development by NASA Ames and her partners. For a review of many other approaches see [Goldhaber-Gordon 97].
