Nanotechnology involves working at the nanoscale level between 1 to 100 nanometers. It can be used to create new materials and devices with unique properties not seen in larger structures. There are two main approaches - top-down and bottom-up. Top-down begins with bulk material and cuts it down to the nano size, while bottom-up builds nanostructures from individual atoms and molecules. Nanotechnology has many applications in medicine like drug delivery, electronics with smaller transistors, renewable energy, and more. However, there are also concerns about potential health effects and environmental impacts that require further research before widespread adoption. The future of nanotechnology looks promising but careful development is needed to address challenges.
Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale. A nanometer is one-billionth of a meter. A sheet of paper is about 100,000 nanometers thick; a single gold atom is about a third of a nanometer in diameter.
The use of nanotechnology in the textile industry has increased rapidly due to its unique and valuable properties. The recent development of nanotechnology in textile areas including textile formation and textile finishing basically based on nanoparticles. Nanoparticles may consist of various elements and compounds and have a length of 1 to 100 nm. Nanoparticles are the most important elements which are now widely used to develop the textile materials and introduce new properties in textiles products.
Nanotechnology is a field that deals with things at molecular level that is as tiny as 10^(-9) of units and finds very useful implementations from cleaning clothes to curing the "incurable"--CANCER.
This document provides an overview of nanotechnology including definitions of nanoscience and nanotechnology. It discusses how nanotechnology works and some unique properties at the nanoscale. Applications of nanotechnology today include products using nanomaterials like batteries, sunscreens, and stain-resistant textiles. The document also outlines potential future applications of nanotechnology in areas like energy production, medicine/drug delivery, electronics, and materials that could be stronger but lighter.

1. Big Things
from a Tiny World
Think small. Think really, really
small—smaller than anything you
ever saw through a microscope at school.
Think atoms and molecules, and now
you’re there. You’re down at the nanoscale,
where scientists are learning about these
fundamental components of matter and are
putting them to use in beneficial ways.
It’s a relatively new area of science that has generated excitement worldwide.
Working at the nanoscale, scientists today are creating new tools, products
and technologies to address some of the world’s biggest challenges, including
● clean, secure, affordable energy
● stronger, lighter, more durable materials
● low-cost filters to provide clean drinking water
● medical devices and drugs to detect and treat diseases more
effectively with fewer side effects
● ighting that uses a fraction of the energy

Because of the promise of
nanotechnology to improve lives
and to contribute to economic
growth, the Federal Government,
through the guiding efforts of the
U.S. National Nanotechnology
Initiative (NNI), is supporting
research in nanotechnology. As a
result of NNI research efforts, the
United States is a global leader in
nanotechnology development.
2. Nano
What??
So what is nanoscience and nanotechnology?
Nanoscience involves research to discover new behaviors and
properties of materials with dimensions at the nanoscale, which
ranges roughly from 1 to 100 nanometers (nm). Nanotechnology is the way
discoveries made at the nanoscale are put to work.
What’s so special about the nanoscale? The short answer is
that materials can have different properties at the nanoscale—some
are better at conducting electricity or heat, some are stronger, some have
different magnetic properties, and some reflect light better or change colors
as their size is changed.
Nanoscale materials also have far larger surface areas than similar
volumes of larger-scale materials, meaning that more surface is
available for interactions with other materials around them.
To illustrate the importance of
surface area, think of a piece of gum
chewed into a ball. Then think about
stretching that gum into as thin a
sheet as possible. The surface, or area
visible on the outside, is much
greater for the stretched out gum
than it is for the wad of gum. The
stretched gum is likely to dry out and
to become brittle faster than the wad due to more
contact at the surface with the air around it.
How small is a nanometer? By definition, one nanometer is a
billionth of a meter, but that’s a hard concept for most of us to
grasp. Here are some other ways to think about how small a
nanometer is:
● A sheet of paper is about 100,000 nanometers thick.
● If you’re a blond, your hair is probably 15,000 to 50,000
nanometers in diameter. If you have black hair, its diameter is
likely to be between 50,000 and 180,000 nanometers.
● There are 25,400,000 nanometers per inch.
● A nanometer is a millionth of a millimeter.

4. Nanoscale materials and effects are found in nature all
around us. Nature’s secrets for building from the nanoscale create
processes and machinery that scientists hope to imitate. Researchers already
have copied the nanostructure of lotus leaves to create water repellent
surfaces being used today to make stain-proof clothing, other fabrics and
materials. Others are trying to imitate the strength and flexibility of spider
silk, which is naturally reinforced by nanoscale crystals. Our bodies and those
of all animals use natural nanoscale materials, such as proteins and other
molecules, to control our bodies’ many systems and processes. In fact, many
important functions of living organisms take
place at the nanoscale. A typical protein such as
hemoglobin, which carries oxygen through the
bloodstream, is 5 nanometers, or 5 billionths of a
meter, in diameter.
Nanoscale materials are all around us, in smoke from
fire, volcanic ash, sea spray, as well as products
resulting from burning or combustion processes.
Some have been put to use for centuries. One

materials—it requires the ability to manipulate and control those
materials in a useful way.
Putting
Techno logy
to Use
Over the past two decades, scientists and engineers
have been mastering the intricacies of working with
nanoscale materials. Now researchers have a much clearer picture of
how to create nanoscale materials with properties never envisioned before.
Products using nanoscale materials and processes are now available.
Anti-bacterial wound dressings use nanoscale silver. A nanoscale dry powder
can neutralize gas and liquid toxins in chemical spills and elsewhere.
Batteries for tools are being manufactured with nanoscale materials in order
to deliver more power, more quickly, with less heat. Cosmetics and food
producers are “nano-sizing” some ingredients, claiming that improves their
effectiveness. Sunscreens containing nanoscale titanium dioxide or
zinc oxide are transparent and reflect ultraviolet (UV) light to
prevent sunburns. Scratch- and glare-resistant coatings are
being applied to eye glasses, windows, and car mirrors.
Entirely new products could result from
nanotechnology too. Research in

focused on finding new ways for
diagnosing and treating disease.
Looking farther into the future, some
researchers are working toward
nanomanufacturing and a
“bottom-up” approach to making
things. The idea is that if you can

material. Laboratory.)
on Nanoscale Behavior
At the nanoscale, objects behave quite differently from
those at larger scales. At the bulk scale, for instance, gold is
an excellent conductor of heat and electricity, but nothing
much happens when you shine light onto a piece of gold.
With properly structured gold nanoparticles, however,
something almost magical happens—they start absorbing
light and can turn that light into heat, enough heat, in fact,
to act like miniature thermal scalpels that can kill unwanted
cells in the body, such as cancer cells.
Other materials can become remarkably strong when built
at the nanoscale. For example, nanoscale tubes of carbon,
1/100,000 the diameter of a human hair, are incredibly
strong. They are already being used to make bicycles,
baseball bats, and some car parts today. Some scientists
think they can combine carbon nanotubes with plastics to
make composites that are far lighter, yet stronger than steel.
Imagine the fuel savings if such a material could replace all
the metal in a car! Carbon nanotubes also conduct both heat
and electricity better than any metal, so they could be used
to protect airplanes from lightning strikes and to cool
computer circuits.

Drug-Delivery Techniques
Dendrimers are a type of nanostructure that can be
precisely designed and manufactured for a wide
variety of applications, including treatment of cancer
and other diseases. Dendrimers carrying different
materials on their branches can do several things
at one time, such as recognizing diseased cells,
diagnosing disease states (including cell death), drug
delivery, reporting location , and reporting outcomes
of therapy.
Water-Filtration Techniques
Researchers are experimenting with
carbon nanotube-based membranes
for water desalination and nanoscale
sensors to identify contaminants
in water systems. Other nanoscale
materials that have great potential
to filter and purify water include
nanoscale titanium dioxide, which is
used in sunscreens and which has been
shown to neutralize bacteria, including
E. coli, in water.

7. ons and Products
Nanofilms
Different nanoscale materials can be used in thin
films to make them water-repellent, anti-reflective,
self-cleaning, ultraviolet or infrared-resistant, anti-
fog, anti-microbial, scratch-resistant, or electrically
conductive. Nanofilms are used now on eyeglasses,
computer displays, and cameras to protect or treat
the surfaces.
Nanotubes
Carbon nanotubes (CNTs) are
used in baseball bats, tennis
racquets, and some car parts
because of their greater
mechanical strength at less
weight per unit volume than
that of conventional materials.
Electronic properties of CNTs
have made them a candidate
for flat panel displays in TVs,
batteries, and other electronics.
Nanotubes for various uses
can be made of materials other
than carbon.

8. Technological
IMPACTS
All technologies have impacts on our lives, and along
with the benefits, there may be risks. The NNI funds research to
help identify positive as well as negative impacts of nanotechnology, so that
the benefits can be realized and steps can be taken to avoid undesirable or
unintended impacts. Research on environmental, health, and safety impacts,
as well as other societal impacts, are important areas of funding for the NNI.
Work funded by agencies such as the National
Institutes of Health, the National Science Foundation,
and the Environmental Protection Agency is helping
scientists to better understand nanoscale materials
and to identify unique safety concerns that may be
associated with them.
Knowledge like this can guide researchers and

disposal.
A few words about risk. Risk, according to experts, involves two factors—
hazard and exposure. If there is no exposure, even a hazardous material
does not pose a risk.
Scientists have found indications, however, that certain nanoscale materials
need to be handled with caution. The National Institute of Occupational
Health and Safety has recommended that employers take appropriate
precautionary measures for handling new materials—including engineering
controls, administrative controls, and personal protective equipment—to avoid
worker exposure to nanoscale materials.
At the same time that some precautions are necessary, researchers are
finding that nanomaterials could provide potential solutions to risks from
other technologies and materials. With government funding, for instance,
Rice University researchers recently discovered that magnetic interactions
between ultra small (nanoscale) specks of rust could help to remove
arsenic from drinking water. Thousands of cases of arsenic poisoning are

Social scientists, ethicists, and others are

nanotechnology will help to identify the
positive and potentially negative impacts, so
that, again, we can realize the benefits and minimize or avoid undesirable
effects.
Into the Future
Today, many of our nation’s most creative scientists and
engineers are finding new ways to use nanotechnology
to improve the world in which we live. These researchers
envision a world in which new materials, designed at the atomic and
molecular level, provide realistic, cost-effective methods for harnessing
renewable energy sources and keeping our environment clean. They see
doctors detecting disease at its earliest stages and treating illnesses such as
cancer, heart disease, and diabetes with more effective and safer
medicines. They picture new technologies for protecting both our military
forces and civilians from conventional, biological, and chemical weapons.
Although there are many research challenges ahead, nanotechnology
already is producing a wide range of beneficial materials and
pointing to breakthroughs in many fields. It has opened scientific
inquiry to the level of molecules—and a world of new opportunities.
Sam Stupp and colleagues at the Feinberg
School of Medicine at Northwestern
University are using nanotechnology to
engineer a gel that spurs the growth of
nerve cells. The gel fills the space between
existing cells and encourages new cells to
grow. While still in the experimental stage,
this process could eventually be used to
re-grow lost or damaged spinal cord or
brain cells.
