Imagine a world where diseases are treated at the molecular level, electronics become smaller yet more powerful, and environmental pollution is cleaned using nano-sized materials. For India, with its rapidly growing tech sector and healthcare challenges, this isn’t science fiction but the transformative power of nanotechnology.
Nanotechnology involves the study and manipulation of nanomaterials, operating at a remarkably small scale—a nanometer is just a billionth of a metre. At this size, materials behave in unique ways, and understanding these properties is leading to groundbreaking advancements in medicine, electronics, energy, and manufacturing sectors that are vital to India’s development.
By exploring new developments in nanotechnology, industries such as healthcare and manufacturing benefit from increased innovation and efficiency. This is particularly relevant for India’s growing tech hubs in Bengaluru, Hyderabad, and Pune, where research in this field is accelerating.
The integration of artificial intelligence (AI) into nanotechnology is pushing the boundaries even further. AI speeds up research, enhances precision, and allows scientists to develop solutions that were once impossible. This approach is fundamental in improving various nanotechnology applications, enabling industries to create advanced products. The potential is limitless with inventions ranging from cancer-fighting nanobots to AI-powered nano-filters for clean water—the latter being especially important for addressing water purification challenges across India.
Nanotechnology is not a completely new phenomenon as its roots stretch back to the early 1980s. Significant milestones in this field highlight researchers’ exploration of molecular and atomic behaviours at this nanometre scale. Today, its applications span across industries, making it an area of study integrating science, engineering, and technological development.
At its core, nanotechnology is the manipulation of matter at the nanoscale, which results in the production of materials and technologies with unique properties. Through nanotechnologies, engineers can produce new nanomaterials that enable increased functionality across different applications and industries.
Due to the significant changes in atomic structure and composition at this scale, nanotechnology has enabled ground-breaking advances in both scientific and industrial sectors.
To better understand the scale of nanotechnology, consider the following comparisons:
A red blood cell is about 7,000 nanometres in diameter
A single DNA strand measures about 2.5 nanometres
A sheet of paper is approximately 100,000 nanometres thick
A strand of human hair is about 80,000 to 100,000 nanometres wide
At such a small scale, nanotechnology is capable of interacting with biological and molecular systems uniquely, leading to beneficial applications in both medicine and science.
The concept of nanotechnology was first articulated by physicist Richard Feynman in his 1959 lecture titled “There’s Plenty of Room at the Bottom.” In it, Feynman envisioned a future where scientists would manipulate individual atoms to create new materials. The term “nanotechnology” was later coined by Norio Taniguchi in 1974, and by the 1980s, tools like the Scanning Tunneling Microscope (STM) allowed scientists to actually see and manipulate atoms. This highlights the role of engineering in nanotechnology, aiming to create more effective nanoscale devices and coatings.
Advancements in tools like the STM have enabled the development of nanostructures, expanding the scope of technology significantly. Since then, nanotechnology has evolved rapidly, leading to breakthroughs in medicine, computing, and environmental science.
In India, institutions like the Indian Institute of Technology (IIT) and the Indian Institute of Science (IISc) have been at the forefront of nanotechnology research, contributing significantly to global advancements in this field.
