What is nanotechnology essay?
Nanotechnology Essay
Nanotechnology is the
study of extremely small things
and is used in the fields of chemistry, biology, physics, materials science, and engineering. Nanotechnology is measured on what is called a nanoscale, also known as a nanometer which is one billionth of a meter.
Is nanotechnology safe for humans?
Out of three human studies, only one showed a passage of inhaled nanoparticles into the bloodstream. Materials which by themselves
are not very harmful could be toxic
if they are inhaled in the form of nanoparticles. The effects of inhaled nanoparticles in the body may include lung inflammation and heart problems.
How is nanotechnology used in everyday life?
Nanotechnology has an influence on almost all sectors of food and agricultural systems, such as food security,
disease treatment delivery
methods, new tools for molecular and cellular biology, new materials for pathogen detection, and protection of the environment.
Why is nanotechnology used?
Nanotechnology is being used
to reduce the cost of catalysts used in fuel cells to produce hydrogen ions from
fuel such as methanol and to improve the efficiency of membranes used in fuel cells to separate hydrogen ions from other gases such as oxygen.
What are the dangers of nanotechnology?
