a commercial or industrial objective.
2. Electronic or digital products and systems
considered as a group: a store specializing in office
3. Anthropology The body of knowledge available to a
society that is of use in fashioning implements,
practicing manual arts and skills, and extracting or
collecting materials.
★Wʜᴀᴛ ɪs Nᴀɴᴏᴛᴇᴄʜɴᴏʟᴏɢʏ?
1. a technology executed on the scale of less than 100 nanometers, the goal of
which is to control individual atoms and molecules, especially to create
computer chips and other microscopic devices.
1. the manipulation of matter on an atomic or molecular scale.
1. the science of manipulating on an atomic or molecular scale especially to
build microscopic devices (as robots).
★Wʜᴀᴛ ɪs Nᴀɴᴏᴛᴇᴄʜɴᴏʟᴏɢʏ?
Nanotechnology is "the
manipulation of matter with at least one
dimension sized from 1 to 100 nanometres." --Wikipedia
1 millimetre : 1,000,000 nanometres.
Thus, nanotechnology involves manipulating matter at an
extremely small scale, such that using the regular microscope
(i.e. the one we have in school), we would still be unable to
study nanotechnology.
It includes:
→ surface science; organic chemistry; molecular biology;
semiconductor physics; microfabrication
→ much more.
★Wʜᴀᴛ ɪs Nᴀɴᴏᴛᴇᴄʜɴᴏʟᴏɢʏ?
Nanotechnology is the engineering of functional systems at the
molecular scale. This covers both current work and concepts
that are more advanced. In its original sense, nanotechnology
refers to the projected ability to construct items from the
bottom up, using techniques and tools being developed today
to make complete, high performance products.
Two main approaches are used in nanotechnology. In the
"bottom-up" approach, materials and devices are built from
molecular components which assemble themselves
chemically by principles of molecular recognition. In the "topdown" approach, nano-objects are constructed from larger
entities without atomic-level control.
☀Usᴇs ᴏғ Nᴀɴᴏᴛᴇᴄʜɴᴏʟᴏɢʏ
Currently, nanotechnology is not all futuristic and advanced, but it has made its
name. With articles about it being able to cure cancer, making nuclear
weapons smaller, acting as weapons, being used for water and air filtration,
its all not done yet. These are all beliefs. But this is the potential of
nanotechnology. The clothing industry, for example, is starting to feel the
effects of nanotechnology. Eddie Bauer is currently using embedded
nanoparticles to create stain-repellent khakis.This is putting stain removal
companies out of business.

Self-cleaning household products
Spraying a nano-chemical onto the grime in your kitchen and watch it disappear and
practically never come back, since many nano-chemicals also prevent grime from
accumulating, is not too far away.
Researchers have also developed nanocomposites, a cluster of nanoparticles from
different elements that can, among other things solve the pollution problem. The
Pacific Northwest National Laboratory, for example, has discovered how to alter
silica particles so that they attract and capture toxic particles in water. This will keep
pollution at a very minimal level, so that fewer damages will be caused every year
due to global warming.

Fact: You are putting nanoparticles next or even on yourself everyday. Example?
Certain sunscreen brands have incorporated nanotechnology into their products; the
use of molecularly-engineered materials means that these sunscreens are much
more effective as nanoparticles are especially good when it comes to UV rays. Their
minute particle size enables them to cover more skin with less cream base and since
they spread more easily, you use less of the sunscreen and theoretically save
money. When it comes to food and other sensitive products, plastics and packaging
industries aren't blind to the fact that a healthy dose of nanotechnology will do them a
lot of good. They can enable their products to last longer and perform better in many
ways by simply tweaking the molecules around a little bit!

Medical Field
Scientists have developed a type of synthetic bone(based on nanoparticles simply by
engineering the components that real bone is made of. AngstroMedica has taken
calcium and hydroxyapatite, a phosphate composite, broken them into their
molecular components, and then made minor adjustments to those components. The
result: identical to a natural bone in both structure and composition and makes an
excellent synthetic substitute in areas where natural bone is missing or broken
beyond repair. This is just the tip of the iceberg. Nanotechnology will be advanced,
enhanced, refined, mastered, and perfected. Our lives will be much more convenient,
and we will be able to save a lot of money due to nanotechnology research.

``What kind of impact does nanotechnology have?
Nanotechnology can either potentially help us or
disadvantage/destroy us, with cancer treatment as an
example of help and nuclear weapons as an example of
potential harm.
``Does it impact us in our daily lives? If so, how?
As a matter of fact, nanotechnology does not directly impact our
daily lives, but it is incorporated into our lives. For example,
some of the thread on your shirt would have been created and
binded using Nanotechnology! (More on dis later)

The good side :3
Nanotechnology is most often used to create stronger,
lighter materials by binding materials at a microscopic level.
For example, nanotechnology is used to create better sports
equipment ranging from golf balls to protective gear. Even
fashion designers use nanotechnology to make fashionable
yet practical clothing! ^^

The awkward moment of doom
when humans use it for bad stuff.
No, seriously. Although nanotechnology helps make your
underwear, nanotechnology is also known for increasing the
reaction effect from particles. Kinda like exaggeration. For
example, a bomb that would explode with 1 unit of force could
explode with a lot more force with nanotechnology.
Nanotechnology can increase the risk of destroying Singapore
reaaaally easily. Hence, bombs and nanotechnology do NOT
go well together and it is strongly suggested
that you do not try. :P

Talking about nutshells.
In a nutshell, nanotechnology has impacted us by creating
stronger, lighter and more practical materials for us to use. It
has sparked many discussions and debates both in the world
and online. Many people have different opinions on the
possible impact of nanotechnology, what will happen in the
future and whether us humans should or should not continue
using nanotechnology to our benefit.
I do not understand why i put in so many weird images in this section. Never ask.
