Nanotechnology Info
Nanotechnology originates from
the Greek word meaning “dwarf”. A nanometre is one
billionth (10 -9)
of a metre, which is tiny, only the length of ten hydrogen atoms, or
about one hundred thousandth of the width of a hair! Although
scientists have manipulated matter at the nanoscale for centuries,
calling it physics or chemistry, it was not until a new generation of
microscopes were invented in the nineteen eighties in IBM, Switzerland
that the world of atoms and molecules could be visualized and managed.
In simple terms, nanotechnology can be defined as
‘engineering at a
very small scale’, and this term can be applied to many areas
of
research and development – from medicine to manufacturing to
computing,
and even to textiles and cosmetics. It can be difficult to imagine
exactly how this greater understanding of the world of atoms and
molecules has and will affect the everyday objects we see around us,
but some of the areas where nanotechnologies are set to make a
difference are described below.
