Nanotechnology involves manipulating and controlling nanoparticles, which are particles so small they cannot be seen with the naked eye and are measured in nanometers. Nanotechnology improves materials, medicine, and other areas by modifying nanoparticles. It allows for things like silver nanoparticles that release ions to kill bacteria, nanogenerators that convert mechanical energy to electricity, nanocomposites that mix nanoparticles into other materials, nanofibers with special properties, and potential future nanobots operating at the microscopic scale.

3. /ˌnænəʊtekˈnɒlədʒi/
Nanotechnology is the manipulation, control, and use of
nanoparticles. Nano-particles are impossible to see with
the naked eye because they are so small that one
nanometer is a billionth of a meter. The use of
nanotechnology helps to improve the quality of material,
medicine, etc. by modifying the nanoparticles.

4. Some Nano-terms.
Silver nanoparticles
have unique optical,
electrical, and thermal
properties . They
continuously release a low
level of silver ions to provide
protection against bacteria .
Nanogenerator is a
prototype nanometer-scale generator that produces
continuous direct-current electricity by harvesting
mechanical energy from such environmental sources as
ultrasonic waves, mechanical vibration or blood flow
Nanocomposites
are materials that
incorporate nanosized
particles into a matrix
of standard material.
Nanofibers are a
new class of material
with special
properties that make
them suitable for a
wide range of
applications.
Nanobots are
incredibly tiny robots,
down at a microscopic
scale.
