nanotechnology has become the subject of modern science and has received a lot
of attention and became at the forefront of technologies today and in the
future.
Nanotechnology has great importance in
improving products, treating diseases, and serving humanity in all areas of
life. In addition, it gives great hope for future scientific revolutions in
physics, chemistry, biology, engineering, and others.
What
is Nanotechnology?
Nanotechnology
refers broadly to a field of applied science and technology that studies
nanoparticles, understands and monitors matter between 1 and 100 nanometers,
which can be used in all different scientific fields, such as physics,
chemistry, biology, materials science, and engineering.
It is worth mentioning
that the term nanotechnology relates to a basic understanding of the physical,
chemical and biological properties on atomic and molecular scales.
Nanotechnology includes
imaging, measurement, modeling, and material handling at the nanoscale to
create functional materials and systems with unique capabilities.

Nanoscience and Nanotechnology
Nanoscience is defined as the science that deals with the study of the
basic principles of molecules and compounds measuring less than 100 nanometers.
A nanometer refers to a unit of
measurement equal to (10-9) meters.
Nanotechnology is defined as the technology that deals with materials and
tools in the nanoscale size (1-100) nm, in the production of innovative
materials and devices with new and distinctive characteristics. It can be used
in various fields and scientific applications.
The Benefits of Nanotechnology
Nanotechnology provides many
benefits in many areas of life, it helps to improve many technological and
industrial sectors to a large extent, such as information technology, energy,
medicine, national security, environmental science, food safety, and many
others.
Nanotechnology also adapts material
structures at very small scales to achieve specific properties, through which
they can strengthen the effectiveness of materials, while being lightweight,
more durable, reactive and entangled.
Many everyday commercial products on
the market rely on nanotechnology. The transparent nanoparticles or membranes
on computer screens, cameras, glasses, windows, and other surfaces can help
make them waterproof, anti-reflective, resistant to UV or IR radiation, or
scratch-resistant, or conductive to electricity.
Nanotechnology has also entered into
consumer products, where billions of microscopic nanowhiskers - each about 10
nanometers long - have been molecularly attached to natural and synthetic
fibers to add stain resistance to clothing and fabrics.
Zinc oxide nanocrystals have also
been used to make invisible sunscreens, they protect against ultraviolet
radiation and silver nanocrystals have been included in bandages to kill
bacteria and prevent infection.
The Significance of
Nanotechnology Education in Modern Society
As a result of the importance of
nanotechnology, the countries of the world in general and the developed world,
in particular, have been very interested in nanotechnology and they think to
introduce the leading nanotechnology in the field of teaching and learning.
Nanotechnology topped the list of
scientific and research interests in most countries of the world.
Many countries during the past few
years established programs and research units, academic and research institutes
but the steady growth of nanotechnology is a challenge for the scientific
community interested in universities and technical colleges to prepare the
workforce to provide future career opportunities in this field.
Many developed countries have
embedded nanotechnology
applications in the curriculum.
The United States is one of the
first countries to reshape the curriculum to include this field in order to
prepare and guide learners in the future.
The United States also paid great
attention to teaching nanotechnology in schools and universities and training
teachers on how to teach nanoscience and nanotechnology.
Nanotechnology education is an
urgent necessity in the 21st century, in the light of technical and scientific
acceleration and great competition among nations.
Many conferences and seminars have
pointed to the need to introduce nanotechnology in the curriculum so that
students do not feel the gap between the school and the reality they live in.
Nanotechnology is considered as an
integral part of "Science, Technology,
Engineering, and Mathematics (STEM) education". Just as engineering
practice is no longer limited to university students, so also nanotechnology.
Everyone - including children,
teachers, and graduate students - can benefit, enjoy and learn this technology.
It is clear from the above that the
importance of teaching nanotechnology in different stages of education and
teacher training is the first step in order to achieve nanotechnology.
This includes concepts and
applications of nanotechnology in curricula, training of teachers and science
teachers in particular, and training them on how to teach nanoscience and
nanotechnology research.

Nanotechnology
in Medicine: Scientists have been able to make accurate machines
of the size of blood cells to treat many diseases that require surgery such as
blockages within the arteries, as well as tumors.
Nanotechnology has
helped to detect some diseases through a "Nanobiotix" sensor. In
addition, it has been used in the treatment of cancer, where gold-plated
nanoparticles are used to destroy cancer cells.
Italian researcher Silvano
Dragonieri from the University of Bari invented an electronic nose using carbon
nanotubes that diagnose cancer tablets by analyzing the air coming out of the
lungs during the exhalation process.
Nanotechnology
in the industry: Nanotechnology
is used in the smart clothing industry that produces energy or removes dirt and
germs by itself, as well as in the manufacture of solid materials outweighs the
hardness of steel with a lightweight.
Nanotechnology is also used in the
manufacture of dust-repellent and non-conductive glass so-called 'active glass'
or 'self-cleaning glass' capable of cleaning itself from dust and water
droplets and the manufacture of three-dimensional screens characterized by
transparency and flexibility.
Nanotechnology has also helped to
improve the aircraft and automobile industry through the use of more powerful,
flexible, lighter and less fuel-efficient nanostructures as well as make
lighter, flexible and powerful sports products such as tennis and hockey
rackets.
Nanotechnology has also been
involved in the manufacture of refrigerators, washing machines, and
