Nanotechnology is a science that specializes in developing and applying objects ranging in size from a few to several hundred nanometers. The forefather of nanotechnology can be considered the Greek philosopher Democritus. He first used the word atom to describe the smallest particle of matter (CK-12, 2022). An example of the first use of nanotechnology can be called the invention of photographic film in 1883 by George Eastman (Bellis, 2019). Nanomaterials manufacture protective and light-absorbing coatings, transistors, light-emitting diodes, and medical equipment. Biotechnology is a science that studies the possibility of using living organisms or their metabolic products to solve some technological issues.
An example of nanotechnology is the recent development of the artificial retina. The Israeli company Nano Retina is developing an interface connecting directly to the eye’s neurons. This is an important invention because it will transfer the result of neural stimulation to the brain, replacing the retina and restoring people’s vision. The company was founded by Israeli engineer and inventor Yossi Gross. Further applications of the artificial retina can be considered the restoration of vision for blind people and augmented reality. The invention has now been tested on a blind chicken, allowing it to see the light. This example is the most promising in developing an artificial retina and will soon be able to be tested in safe conditions on humans. This will positively impact society because it will allow blind people to see and move more confidently without anyone’s help. Among the dangers of the invention, one can single out the possibility of damage to the human eye and side effects from augmented reality in the form of dizziness.
On the negative side, nano retina can badly affect society because such treatment will be expensive, and not everyone can afford it, leading to social injustice. However, from an ethical point of view, the invention will not be able to cause concern in society.
People have been using nano and biotechnologies in everyday life for a long time. An example is modern nanotransistors inside electronics. Most people will not be able to work or study without the help of a computer, so nanotechnology has a direct impact on people’s lives.
