JAMES M. TOUR*
ABSTRACT
While investors are often proficient in assessing the business aspects of their technology
investments, the technology horizon assessment is illusive. In this article, Professor James Tour
describes a methodology to categorize different nanotechnologies into one of three types: passive, active,
or hybrid nanotechnologies. The three technology types each have a characteristic timeline for expected
product delivery and, in this manner, the science or engineering layperson can make the technology
horizon evaluation. Examples of each of the three technology types are provided from our own
laboratory  using carbon nanotube rubber composites, nanocars, and silicon-molecule devices,
respectively.
I.  INTRODUCTION
escribed here is a tool to pigeonhole a specific nanotechnology in order to gauge its
commercialization horizon (0-5 years vs. 15-50 years vs. 7-12 years) based on the
nanotechnology type: a passive, active or hybrid nanotechnology, respectively. In my seminars
to the technology lay (in my view) public including lawyers and entrepreneurs, they have found this topic
helpful as they navigate the investment landscape.
The truly exciting developments in nanotechnology, the ones that are science fiction-like in vision,
are often 30-50 years away, or even 100 years out, so my suggestion is to invest elsewhere unless you
have a dynasty-like horizon and the capital to sustain the vision at each round throughout the century.
The passive nanotechnologies sound more mundane, but they can be the capital-generating apparatus for
diversified portfolios. This is naturally only one method of several that is needed in seeking the one in ten
high-risk investments that will bring substantial return. There are many factors that I will not consider
