2. Nanoengineering is a branch of engineering that deals with all aspects of the
design, building, and use of engines, machines, and structures on the nanoscale. At its core,
nanoengineering deals with nanomaterials and how they interact to make useful materials,
structures, devices and systems.
Nanoengineering is not exactly a new science, but, rather, an enabling technology
with applications in most industries from electronics, to energy, medicine, and
biotechnology.

4. Nanotechnology refers to the branch of science and engineering devoted to designing,
producing, and using structures, devices, and systems by manipulating atoms and
molecules at nanoscale
 Nanotechnology is hailed as having the potential to increase the efficiency of
energy consumption, help clean the environment, and solve major health problems.

5. Micro technology
• Micrometer (also referred to as micron) is a millionth of a
meter (10 ^-6 m). Micro technology is used in
mnufacturing miniaturized systems or objects at
micrometer scale. Printer heads, sensors and integrated
circuits are examples for micro scale products.
Nanotechnology
• Nano is a Greek word meaning ‘Dwarf’ and nanometer is
a billionth of a meter (10^-9m ). Nanotechnology is
designing, developing or manipulating at nanometer (a
billionth of a meter) scale. The size of the dealing object
should be less than hundred nanometers, at least in one
dimension, to call something to be nanotechnology.

7. Types of Nanotechnology
Top-down or bottom-up processes and dry or wet working environments are used to categorize
the many forms of nanotechnology
Descending (top-down):
Mechanisms and structures are miniaturized at the nanometer scale - from one to 100 nanometers - this is the
most frequent trend, especially in the electronic field.
Ascending (bottom-up):
By mounting or self-assembling a nanometric structure, you form a larger mechanism than what you started
with.
Dry Nanotechnology:
Dry Nanotechnology: It does not require humidity to manufacture structures made from coal, silicon, inorganic
materials, metals, and semiconductors.
Wet Nanotechnology:
This technology utilizes biological systems that exist in aqueous environments, including genetic material,
membranes, enzymes, and other aspects of the cell.

8. Advantages of Nanotechnology
 Nanotechnology can actually revolutionize a lot of electronic products, procedures, and applications. The areas
that benefit from the continued development of nanotechnology when it comes to electronic products include nano
transistors, nano diodes, OLED, plasma displays, quantum computers, and many more.
 Nanotechnology can also benefit the energy sector. The development of more effective energy-producing, energy-
absorbing, and energy storage products in smaller and more efficient devices is possible with this technology. Such items
like batteries, fuel cells, and solar cells can be built smaller but can be made to be more effective with this technology.
 Another industry that can benefit from nanotechnology is the manufacturing sector that will need materials like
nanotubes, aerogels, nano particles, and other similar items to produce their products with. These materials are often
stronger, more durable, and lighter than those that are not produced with the help of nanotechnology.
 In the medical world, nanotechnology is also seen as a boon since these can help with creating what is
called smart drugs. These help cure people faster and without the side effects that other traditional drugs have.
 You will also find that the research of nanotechnology in medicine is now focusing on areas like tissue
regeneration, bone repair, immunity and even cures for such ailments like cancer, diabetes, and other life threatening
diseases.

9. Nanoelectronics – Nanotechnology in Electronics
The term nanoelectronics refers to the use of nanotechnology in electronic components. These components are
often only a few nanometers in size. However, the tinier electronic components become, the harder they are to manufacture.
Nanoelectronics covers a diverse set of devices and materials, with the common characteristic that they are so
small that physical effects alter the materials 'properties on a nanoscale – inter-atomic interactions and quantum mechanical
properties play a significant role in the workings of these devices
Nanocoatings
The term nanocoating refers to nanoscale (i.e. with a thickness of a few tens to a few hundreds of nanometers)
thin-films that are applied to surfaces in order create or improve a material's functionalities such as corrosion protection,
water and ice protection, friction reduction, antifouling and antibacterial properties, self-cleaning, heat and radiation
resistance, and thermal management.
Nanocoatings offer significant benefits for applications in the aerospace, defense, medical, marine, and oil
industries, have driven manufacturers to incorporate multi-functional coatings in their products.
Nanosensors
Nanosensors are tiny sensors that are designed to measure physical, chemical, biological, or environmental
information at the nanoscale level and transfer it into data for analysis. They are made from nanomaterials and have unique
properties, such as high surface-to-volume ratio, that make them ideal for sensing applications. Nanosensors are used in a
wide range of fields, such as healthcare, environmental monitoring, and security, and have the potential to revolutionize the
way we detect, measure, and respond to various signals and stimuli.
Nanotechnology in Space
The development of nanomaterials could lead to lighter and more efficient fuel storage, and the use of nanoscale
structures in propulsion systems could increase their performance. Additionally, nanotechnology could be used in sensors and
controls for improved spacecraft navigation and maneuverability.
Nanotechnology can lead to the creation of miniaturized devices and instruments that can be used for space
missions. This will result in smaller and lighter payloads, which will reduce launch costs and increase the efficiency of space
missions.

10. Disadvantages of Nanotechnology
 Included in the list of disadvantages of this science and its development is the possible loss of jobs in the
traditional farming and manufacturing industry.
 You will also find that the development of nanotechnology can also bring about the crash of certain markets
due to the lowering of the value of oil and diamonds due to the possibility of developing alternative sources of energy that
are more efficient and won’t require the use of fossil fuels. This can also mean that since people can now develop products
at the molecular level, diamonds will also lose its value since it can now be mass produced.
 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.
