Abstract
With the new developments of nanotechnology nowadays, we do not know all the
consequences. That is why nanotechnology is often to be considered as something
dangerous and unknown. It can bring us a lot of opportunities for new
technological developments, but it also can be dangerous.
This report describes what nanotechnology is, some future concepts, and the
disadvantages of the new developments. It explains why nanotechnology is
something that needs to be reconsidered.
The report concludes that privacy issues and health concerns are the main issues
among nanotechnology. Furthermore, social scientists and other people are kept
outside the research, which will lead to misunderstandings. We are blinded by new
technology developments, and not thinking about the consequences.

Introduction
1.1. Nanotechnology in our Next Nature
We live in a world that humankind has made for us, and where technology is
number one. All the products, buildings, everything around us, are made by
humans, with the current technology. Engineers are coming up with even smaller
technology products than before. The thing is, we don’t even know what old nature
looks like; how the world looks like without human intervention. Human kind has
developed a new form of nature: Next Nature. This name is given by different
designers, to make the problem of our technology culture and nature clear. [4]
The development of nanotechnology is part of our next nature. Scientists are
coming up with new opportunities in medicine, electronics and materials. It will
realize their wildest dreams, but what are the consequences of these
developments? There is much debate around the developments of nanotechnology:
what kinds of environmental impacts will it have, and what about the privacy of
people and society? People are a bit afraid of the new developments among
nanotechnology, because it is unknown to them and very abstract. Maybe
nanotechnology can bring us a lot of opportunities and advantages, but it also can
be dangerous.
This brings us to the next statement: We need to reconsider the developments
among nanotechnology.

2.1. What is nanotechnology?
We start with a definition of nanotechnology from a leading group in
nanotechnology:”Nanotechnology is the construction and use of functional
structures designed from atomic or molecular scale with at least one characteristic
dimension measured in nanometers”. [5] So what they mean when they speak of
nanotechnology? They manipulate the molecule structure of any atom to get unique
properties, which you can implement in any material or device. This is done on a
very small scale, the size of one billionth of a meter. Only in this small scale can the
molecules exhibit improved and different properties, which we can use in different
applications.
A molecule is the smallest part of a molecular substance, such as water or oxygen.
A water molecule consists out of two water molecules (H2) and one oxygen
molecule (O). Figure 1 [9] shows a water molecule. Almost everything around us
consists of molecules.

2.2. Debate-provoking nanotech products
2.2.1. The twitter implant
Fifteen years from now, in 2016, a twitter implant
(figure 2) [6] will be available which will register
everything you do: your location, your favorite
music, your mood and even what happens inside
your body. You connect the implant to your iPhone
and you can decide what you want to share with the
world. Everyone knows Twitter, and from the time it
was released in 2008, everybody is sharing their
tweets and spending hours behind the screen to
follow people. Now it will become much easier! [6]

2.2.2. Nano-lift – Physical Photoshop
Plastic surgery is an emerging trend. A lot of people
want to change their face or body to look even better.
In the future this will be even easier with the nano-lift
(figure 3) [7]. Your face has to be injected with a grid
of tiny magnetic nano particles. With the nano-lift,
which is a magnetic stick, you can adjust these
particles at home and change the shape of your face
physically. [7]

2.2.3. Programmable wine
You have a lot of different wines with different
flavors. With the speculative nanotech wine you can
have all these wines in one bottle (figure 4) [8]. This
wine is filled with nano sized flavor capsules, which
will open by influence of microwaves. The time and
the wattage will open different capsules, which will
create different wines. [8]
Figure 4: Programmable wine [8]
2.3. Debate among nanotechnology
2.3.1. Manipulation
Manipulation is still a dangerous thing because we do not know exactly what the
consequences of it may be. Manipulation is changing the structure of the molecule
to get better, different properties. With manipulating the molecule structure, you
create nanoparticles which can be chemically reactive and can harm biological
pathways. Normal harmless substances such as titanium dioxide, can become
reactive when used and manipulated on the nano scale structure. These substances
can burn bacteria at the nano level. If such nanoparticles end up in the lungs of
people or animals, it can damage your health and pass on to other humans or
animals. [1]
2.3.2. Privacy issues
One of the most privacy issue products of nanotechnology, are the implants of
microchips into human bodies. These chips can be of a great benefit to control drug
usage of people or controlling hospital patients. But these chips can be expanded
and sold for other purposes, for example watching your enemy or your cheating
husband. The twitter implant is slightly different, because you can somehow control
your information.

Another issue is that a lot of researchers disagree among each other how far
nanotechnology can go. Some are only thinking about revolutionary concepts, while
others see the ethical issues. Also a lot of research and development of
nanotechnology is kept confidential. A lot of social scientists, who can better
evaluate the consequences of new technology on society, are kept outside the new
developments. [1]
2.3.3. Next Nature
Nanotechnology is part of our next nature. It is very unclear what it means and
what you can do with nanotechnology. People are a bit afraid of the nanotechnology
developments because it is unfamiliar to them and abstract. This is also the case
with other technological products. Technology is not associated with calm and
peaceful, so this has to change. This next nature, this technology world where we
are living in now, will make people more afraid. To change this we need to get
people more familiar with the new technological developments.

Conclusion
Nanotechnology has to deal with the manipulation of the structure of molecules, in
order to get unique properties, which you can implement in any material or
product. Examples of nanotech products are the twitter implant, the nano-lift,
where you can physically photoshop your skin, and the programmable wine.
Nanotechnology can bring a lot of opportunities, but it also can be dangerous.
The main issue concerning nanotechnology is the privacy issues. Secondly, social
scientists and other people are kept outside the research and developments of
nanotechnology. This will lead to misunderstandings and an unknown field for
society. Thirdly, while manipulating we create new substances that can be harmful
for our health.
The main conclusion is that we are blinded by technology and not thinking about
the consequences and the laws of old nature. So the developments among
nanotechnology need to be reconsidered in the future.
