Nowadays, you will not surprise people with the word “Nanotechnology”, yet many people do not even realize the great impact nanotechnology has on our daily lives. Nanotechnology is modern science, engineering, and technology, which is conducted at the nanoscale (1-100 nanometers). One nanometer is equal to a billionth of a meter. To give you a clear example, a single sheet of newspaper is 100,000 nanometers thick. You should know that atoms and molecules behave completely differently at the nanoscale.
Nanotechnology is an expanding field. Many talented engineers and the best scientists work hard making materials at the nanoscale. When you present content about nanoscience, it has to be informative and understandable to people, as the topic is not that easy. Luckily, it is not a problem to order a professional custom paper, starting with an essay about Lady Macbeth and ending with the latest nanotechnology.
Let’s have a glance on how nanotechnology can impact our lives:
- Faster and more powerful computers, which consume less power. Modern computers have longer-lasting batteries. Circuits, which are made from carbon nanotubes, aim to maintain computer power.
- People get access to much faster, more accurate, and functional medical diagnostic equipment. Have you heard about the technology called “Lab-on-a-chip”, which enables testing in real time and speeds up delivery of urgent medical care? All nanomaterial surfaces, which are used for producing modern implants resist any kind of infection.
- Pharmaceutical products contain nanoparticles, which improve their absorption within our bodies. They are also used to deliver chemotherapy drugs to the affected cancer cells.
- Nanotechnology helps to improve vehicle fuel efficiency. The vehicle parts which are made from nanocomposite materials are lighter, stronger, and more chemically resistant comparing to metal.
- Nanoparticles in fabrics are stain, water, and flame resistance. They do not increase such properties of fabrics as weight, thickness, or stiffness.
- Water filters (15-20 nanometers) are able to remove all viruses and bacteria. This is an innovative cost-efficient water treatment systems. Many countries need urgently to get the quality of drinking water improved
- Carbon nanotubes make our sports equipment stronger and the weight of it lighter.
- Modern sunscreens, which are made from nanoparticles, absorb light more efficiently, including the dangerous ultraviolet range.
- Cosmetics industry suspend and encapsulate various ingredients into nanospheres and nanoemulsions. Specialists claim that they help increase their penetration into our skin. You might not know but many cosmetic products use nanomaterials in some forms. For example, L’Oreal has developed an anti-wrinkle cream, which contains polymer nanocapsules for better delivery of active ingredients into deeper layers of skin.
- Drink bottles are also made from plastics, which contains nanoclays. It gives good resistance to permeation by oxygen and moisture.
- In medicine, nanosensors help to identify particular cells/substances in the body.
These are just a few points on how nanotechnology impacts our lives. New nano-achievements appear almost daily. It is up to you to trust this schiece or avoid it as much as possible.
Is nanotechnology safe?
Nanotechnology has the huge potential to transform people’s lives for the better. We start using cheap, lightweight solar plastics, which makes solar energy widely available. Nanoparticles can clean up toxic chemical spills, as well as air-borne pollutants. Specialists claim that nanomaterials may be used in space exploration.
Despite these positive sides, nanotechnology has a shadow side. It is a new science, and we do not know about its long-term effects of influencing nanoparticles into the environment. At the moment, nanotechnology is unregulated. Companies even do not have to label the products, which contain nanoparticles. In fact, there are no recognized standards for producing and handling nanomaterials.
Many people are suspicious about the potential effects of nanomaterials on our health, planet, and ecosystems. Some studies claim that certain kinds of nanomaterials are quite toxic to algae, invertebrates, and fish. Nanomaterials can be even transferred across many generations in animals and plants.
We have to stay informed about this new technology. People should share what they know with others. The more people know about nanotechnology, the more likely that manufacturers will take into consideration health and safety standards.
