7. Air pollution and remediation (TiO 2 nanoparticle-based pho-
tocatalytic degradation of air pollutants in self-cleaning
systems, nanocatalysts for catalytic converters, nanosensors
for detection of toxic materials . . .)
8. Construction (Nanomolecular structures for water-proof
asphalt and concrete, heat-resistant nanomaterials to block
ultraviolet and infrared radiation, self-cleaning surfaces . . .)
9. Health monitoring (Nanotubes and nanoparticles for glucose,
CO 2 , and cholesterol sensors, and for in-situ monitoring of
homeostasis . . .)
10. Vector and pest detection and control (Nanosensors for pest
detection, nanoparticles for new pesticides, insecticides . . .)
It is important for the international community to work together 203 ch09
to find ways to accelerate the use of these nanotechnologies by less
industrialised countries to meet their critical sustainable develop-
ment challenges. Figure 9.1 shows the NSF projected nanotechnol-
ogy market by 2010–2015; it is clear that materials and electronics
will be the first areas that nanotechnology will find commerciali-
sation opportunities.
9.2 BEYOND MOORE’S LAW
There will be limits to Moore’s Law and how far the current
CMOS-based silicon technology can be pushed. These limits
could arise from fundamental physics or materials science issues,
