Many (perhaps most) scientists would have little quarrel with the basic technical discussions Drexler presented in these two books. His extrapolation of these scientific principles to the direction of future research, however, has become the subject of vigorous and sometimes acrimonious debate. That debate centers on Drexler s belief that bottom-up technology can eventually result in the development of three new and powerful nanoscale devices assemblers, replicators, and nanocomputers. 

Starting from the synthesis of stereoregular and optically active polymers, we reached the idea that inclusion polymerization constitutes one of supramolecular chemistry from a viewpoint of the space effects. Now such a study might be connected to nanotechnology, because the polymerization can produce molecular composite materials, such as molecular wires layers, and so on. The bottom-up technology would be constructed through various...

To give a thorough, rational review of the field of chemical micro-process technology itself, one ideally would like to follow a deductive analysis route, pursuing a bottom-up approach. First, one may provide a definition of micro reactors, then search for the impacts on the engineering of chemical processes, and try to propose routes for exploitation, i.e. applications. Alternatively, for a less comprehensive, but more in-depth description, one could use a top-dovm approach starting with a selected application and try to design an ideal micro reactor for this. 

In general, abatement options are from a bottom-up perspective categorized into emission control technologies, substitution options or efficiency improvements. 

This chapter provides a brief survey of work on bottom-up assembly of high-quality NW building blocks for various applications, ranging from nanoscale electronics and optoelectronics to large-area thin-film technologies.
