1.1- What is Nanotechnology?
• The design, characterization, and application of
structures, devices, and systems by controlled
manipulation of size and shape of materials at
the nanometer scale (atomic, molecular, and
macromolecular scale) ,
• To produce materials with at least one
novel/superior characteristic or property.
CLASSIFICATION
• There are different classification of
nanostructures in nanotechnology. the most popular
mode of namostructureClassification is according to
their dimension on the nano scale which is of the order
of afew neno meters(1-100nm).in a last one dimension
• nanostructures can be described as zero-
dimensional(0D),onedimensional(1D),tow-
dimensional(2D),three-dimensional(3D) nano material

coated with a combination of titanium dioxide
Carbon capture
Pollutants sensors that able to detect lower limits
with low cost
Sensors
Heavy metal decontaminant removes heavy metals
such as lead, cadmium, nickel, zinc, copper,
manganese and cobalt in a neutral pH environment
without using any form of sulphur .
Remediation (decontamination, oil spill
management)
Veolia Water Solutions & Technologies' ceramic
membrane modules, utilizing the CeraMem
technology platform, can be supplied with a variety
of inorganic microfiltration and ultrafiltration
membranes.
Wastewater treatment
Heat distribution e.g. ceramic-like
materials that provide sufficient reliability and
durability of the entire structure
Energy
Drinking water purification
Advantages of Nanotechnology
• Protects drugs from being degraded in the body
before they reach their target.
• Enhances the absorption of drugs into tumors
and into the cancerous cells themselves.
• Allows for better control over the timing and
distribution of drugs to the tissue, making it
easier for oncologists to assess how well they
work.
• Prevent drugs from interacting with normal cells,
thus avoiding side effects.
Disadvantages of Nanotechnology
• Atomic weapons can now be more accessible and made to
be more powerful and more destructive. These can also
become more accessible with nanotechnology.
• Since these particles are very small, problems can actually
arise from the inhalation of these minute particles, much
like the problems a person gets from inhaling minute
asbestos particles.
• Presently, nanotechnology is very expensive and
developing it can cost you a lot of money. It is also pretty
difficult to manufacture, which is probably why products
made with nanotechnology are more expensive.
