Transcript of Nanotechnology

Group 1: Includes the use of nanotechnology to create robots called nanorobots
Basic Information
As said in the name, these robots are very small.
These nanorobots have a lot of potential but at this current stage in research, they aren’t as complete.
One of the things scientists are already doing with these robots is sending them inside the human body.
When someone is treated through the use of nanorobots, the treatment is called nanorobotic treatment.
Group 2: Includes the use of it in everyday substances whether it is to change that substance or use it to create something else.
A couple of examples would be sunscreen, self-cleaning gas, clothing, scratch – resistant coating and antimicrobial bandages.
Medicines are also great examples.
Already, medicines involved with nanotechnology are able to help treat major illnesses/diseases/infections and have better delivery.
These medicines tend to have better delivery because of the employed nanoparticles inside of them. The job of these nanoparticles is to deliver substances to specific cells. If the nanoparticles are programmed to attract to disease cells, the disease can be easily reached and possibly treated.
It will be able to preserve the planet because in the future, scientists will be able to release nanorobots that are capable of purifying water, enriching soil, reconstructing the ozone layer and cleaning up messy situations like oil spills.
Preserving the Planet
1. It makes our lives more secure. Using nanotechnology, we can develop things that could help with diagnostics.
2. It has been able to reduce the use of our limited resources. Without out it, there is a chance that one or more of our resources would have been depleted or at the very least be impacted.
3. It can make materials ten times stronger than steel but with less weight. If it could do this, things such as buildings, vehicles, and weaponry would be stronger and tougher but lighter.
4. It can increase the power of the computers but also make them smaller.
5. It works with various materials such as ceramics, metals, polymers, and biomaterials.
6. Even against the wildest things such as fighting against cancer, nanotechnology can and will help you. The help may be through enhanced medicine or even robotic operations.
Why is it important?
Where is it and what is it currently used in?
At the moment, nanotechnology’s development isn’t very far. Scientists still have many things to discover about it. Like some scientists would say, nanotechnology is still a ‘young’ science. Despite of this, nanotechnology is already used for many things which greatly benefit off of it. The uses of nanotechnology can be divided into two main groups.
Nanotechnology and Cancer
It all started in a conference at California Institute of Technology on December 29, 1959.
At this conference, a physicist named Richard Feynman introduced the ideas behind manipulating and controlling the particles of a substance.
This presentation was called "There's Plenty of Room at the Bottom" and Richard Feynman was titled as the father of nanotechnology.
How It Started
Richard Feynman's ideas came to be called Nanotechnology around 10 years after the conference.
The name was created by a professor named Norio Taniguchi after he explored ultra-precision machining.
The Name
Modern Technology
So, what is Nanotechnology?
The future of nanotechnology is hard to predict since scientists still do not see the limits of it. If it has been so beneficial in its current stage, imagine how beneficial it would be when it is fully unraveled. Without any doubt, it has a bright future in store. In the future, nanotechnology will be able to preserve the planet and further improve dental care, energy sources and whatnot.
The Future
Modern Technology did not begin until 22 years after Richard Feynman's presentation.
It took this long because the microscopes at the time weren't powerful enough to see the individual particles/atoms. The scanning tunneling microscope allowed scientists to do so.
Modern Technology can also be referred to Molecular Nanotechnology.
K. Eric Drexler
K. Eric Drexler was the first person to discover Molecular Nanotechnology
With his invention, Eric wanted to make machines at a scale of atoms.
Based on his research, he published a book called “Nanosystems: Molecular Machinery Manufacturing and Computation “(1992).
Nanotechnology is the science of functional system at molecular scale.
In other words, it’s a study of very small things that can’t be seen through a light microscope.
In this technology, scientists simply play around with the particles/atoms of a substance.
For example, you can make diamond out of hair because both of these substances have similar atoms such as carbon. It may not be the amount of diamond you expected but the concept is what really counts.
When scientists use a nanorobotic treatment to help treat cancer, a very small robot is sent into the human body. This robot will be equipped with a medicine that can be sprayed on the cancer cells to kill them. If the operation is successful, there may be a hope for those who have suffer cancer.
Improved Dental Care
The dental care of one’s country will improve at an extent where repairing teeth, repositioning them, inducing anesthesia, and permanently curing hypersensitivity would be like a walk in the park.
Repairing teeth will be much easier in the future because the dentists will be able to develop a new tooth right in their office.
Repositioning teeth will also be much easier because by that time, scientists would have developed orthodontic nanorobots that could rotate and straighten teeth quickly but painlessly. Thanks to these nanorobots, braces wouldn’t be needed anymore.
Inducing anesthesia would be much easier because by that time, you can confidently say that a group of specialized nanorobots would have been developed. If everything goes according to plan, these nanorobots would be controlled by the dentist. First, they would enter the crown of the mouth and then pass through a bunch of other layers.
Permanently curing hypersensitivity will also be a walk in the park because thanks to nanorobots, dentists could ‘shut’ down the sensitive areas. Even though the cure is permanent, the process is quite quick.
Energy sources will improve in the future because already, scientists have discovered that nanotechnology could be used to develop energy sources that are renewable, less expensive and safer for the environment.

Things that will be developed from nanotechnology and contribute to energy sources:
Nanostructured solar cells
Thin-film solar panels
Windmills with light weight nanostructures
Improved Energy Sources
Examples of Current Energy Sources
Four Generation of Nanotechnology
There are four generations to nanotechnology which was brought across by an U.S. National Nanotechnology Initiative named Mihail Roco.
Now, let us compare the size of this scale to the size of an object. Notice how nanotechnology builds from smaller things into bigger things.

Atom Size
Nanotube Size
Matter Size

In conclusion,
nanotechnology is very useful in our world. It may be a study of small things but it can be used to create bigger things. Without nanotechnology, our lives would be much more difficult. The medicine we take would be less effective without nanotechnology. On a day at the beach, nanotechnology’s improved sunscreen could have prevented you from getting a painful sun burn. It just goes to show how important nanotechnology really is. Thanks to scientists like Richard Ferynm, we have this tool to use. Even though the concept is still not fully ‘awakened’, it already has improved our lives. In spite of this, scientists continue to develop research on nanotechnology for the current and future generations. A bright future waits for the life on Earth.
