Question

Quizplus · Accepted Answer

Nanotechnology is the engineering of materials and devices at the nanoscale, which is typically defined as between 1 and 100 nanometers. It involves the manipulation and control of matter at the atomic and molecular level to create new materials and devices with unique and desirable properties. Option B, "the ability to build objects one atom or molecule at a time," best defines the core concept of nanotechnology. The other options describe different fields of science and technology such as biology, manufacturing, 3D printing, and artificial intelligence, which may have some overlap with nanotechnology but do not fully capture its essence. Nanotechnology refers to the manipulation and engineering of materials at the nanoscale, typically between 1 to 100 nanometers. This involves the ability to control the properties and behavior of materials at this tiny scale. Option B is the most accurate definition of nanotechnology, as it describes the ability to build objects one atom or molecule at a time, which is a fundamental concept in the field. Option A refers to the field of biochemistry, option C refers to biotechnology, option D refers to 3D printing, and option E refers to artificial intelligence. While these fields may overlap with nanotechnology, they do not encompass the full scope of the field.
