Q. Consider the following statements with reference to Nanotechnology:
1. It involves science and engineering of objects in the range of only 1 to 10 nano-meter.
2. An atomic force microscope is used to generate images of nano-scale details on a physical surface.
Which of the statements given above is/are correct?
Answer: B
Notes:
Nanotechnology
- The idea of nanotechnology was born in 1959 when physicist Richard Feynman gave a lecture exploring the idea of building things at the atomic and molecular scale.
- The term ‘Nanotechnology’ was coined in 1974 by Norio Taniguchi of Tokyo Science University to describe semiconductor processes such as thin-film deposition that deal with control on the order of nanometers.
- Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers.
- Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.
- An Atomic force microscope is a scientific instrument that can generate images of nanoscale details on a physical surface by scanning small nanoscale probes.
