Even though there is no generally accepted definition of
nanotechnologies to be defined as distinct discipline there is an
emerging consensus that their advent and development is a growing
in importance factor of the contemporary and future technological
civilization. One of these most fundamental issues we are
confronted with is the compatibility with life itself. From single
cell organisms to humans, carbon is a key building block of all
molecular structures of life. In contrast the man created
electronic industry to build on other elements, of which silicon is
the most common. Both carbon and silicon create molecular chains,
although different in their internal structure. All life is built
from carbon-based chains. As long as the man built technological
products do not directly interfere with the physiology of life the
associated risks from them are relatively easy to identify. They
are primarily in the environmental pollution and the possibility of
upsetting the natural balance of biocoenosis, on a planetary scale.
The basic life functions are still not directly subverted. We can
use TV, computers, drive cars and use other technological utilities
without fear of direct interference with our cellular functions.
This is in particular because all these technological utilities are
many orders of magnitude larger than typical scales of biological
activity. Most of biological activity, from fermentative catalysis
to DNA replication takes place on nanoscale. The situation is
radically different when the technological goals are building
nanoscale size products. All biological processes take place on
nanoscale.
