LESSON 15 - NANOTECHNOLOGY Flashcards
Nanotechnology: from the Greek word nano, meaning “______________” or “_______”
little old man/ dwarf
is the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, material science, and engineering.
Nanoscience
In 1959, he presented the first-ever concept of nanotechnology.
Dr. Richard P. Feynman
he was a Nobel prize-winning American physicist. Known for his contributions in Quantum Physics, quantum electrodynamics, particle physics, as well as quantum computing and nanotechnology.

Dr. Richard P. Feynman
In 1974, he invented the term Nanotechnology at the University of Tokyo.
Norio Taniguchi
He described it as a process which involves the separation, consolidation, and deformation of materials by one atom or one molecule.
Norio Taniguchi
In 1981, he published a paper about basic concepts in nanotechnology
Kim Eric Drexler
In _____e used the term “molecular nanotechnology” or “molecular manufacturing” to distinguish his ideas from other scientists.
1992
In ____- commercial applications of nanotechnology began to increase, such as the use of silver nanoparticles as an antibacterial agent, nanoparticle-based cosmetics in transparent sunscreens, and carbon nanotubes clothing materials which are effective as stain-resistant textiles

APPLICATION OF NANOTECHNOLOGY
Nanomedicine
Electronics
Environment
Consumer products
Sporting goods
An application of nanotechnology in the field of medicine which deals with creating tiny machines to help prevent and treat diseases of the human body.
Nanomedicine
These include activity monitors, chemotherapy, pacemakers, biochips, OTC tests, insulin pumps, nebulizers, needleless injectors, hearing aids, medical flow sensors and blood pressure, glucose monitoring, and drug delivery systems.
Nanomedicine
is the application of nanotechnology to help develop electronic devices to nanoscale and be able to reduce their weight and power consumption, improved display screens on electronic devices to increase the density of memory chips.
