Nanotechnology

Choose the Correct Answer

Correct Answer : Option c

Explanation
Statement 1 is correct: Nanotechnology involves manipulating matter at a near-atomic level to create new materials, structures, and devices. Nanomaterials typically range in size from 1 to 100 nanometers, and at this scale, they exhibit unique physical, chemical, and biological properties. Researching and utilizing these properties is central to technological advancements.

Statement 2 is correct: In the food industry, nanotechnology enhances food safety by using nanosensors to detect infections or contamination during manufacturing, processing, packaging, storage, and transportation. However, incorporating modified nanoparticles in food products increases human exposure to oral nanoparticles. Nanotechnology also enables the study of physical phenomena and the development of new materials and devices within the 1-100 nanometer range, where 1 nanometer equals one-billionth of a meter.

Statement 3 is not correct: The Ministry of Electronics and Information Technology (MeitY), not the Department of Science, has launched several key initiatives to promote research and innovation in nanoelectronics. One of its flagship programs, the Indian Nanoelectronics Users Programme-Idea to Innovation (INUP-i2i), is being implemented at the Centre of Excellence in Nanoelectronics (CEN) across IISc, IIT Bombay, IIT Delhi, IIT Madras, IIT Kharagpur, and IIT Guwahati. This initiative provides researchers and developers across India with access to advanced nanofabrication facilities for conducting research and skill development in nanoelectronics. The Nanotechnology Initiatives Division primarily focuses on fostering an ecosystem for electronics manufacturing in India by supporting cutting-edge research in nanoelectronics, developing products and devices to meet societal needs, and establishing world-class nanofabrication facilities.
