Sci-tech: The wondrous world of science

Nanotechnologyan exciting new frontier

One of the most exciting advances in science during the last couple of decades has been thedevelopment of nanotechnology. It is now finding myriad applications in medicine, food, water

purification, cosmetics, electronics and many other fields. The US has the largest share (28 per cent) inthe nanotechnology market, followed by Japan (24 per cent), and Europe (25 per cent, main playersGermany, France and UK).

Nanomaterials owe their special properties due to their size. They are typically between onenanometre (nm) and 100nm in size. One nanometre is one-billionth of a metre. The relative scale can

be judged from the statement that a nanometre is of about the same proportion to a metre, as a marbleis to the earth.

The emergence of this field was triggered by two major advances in the 1980s. The first was thedevelopment of the scanning tunneling microscope in the early 1981 which allowed images to be seenat the atomic level. The second was a serendipitous discovery of molecular carbon footballs in 1985

by Harry Kroto, Richard Smalley, and Robert Curl, who together won the 1996 Nobel Prize inChemistry. A host of developments followedcarbon nanotubes, thin carbon sheaths (graphene), anddifferent methods to develop useful nanomaterials.

The applications in medicine include improved drug delivery of nanomedicines due to improvedabsorption in the human body. Their use in medical imaging can provide better pictures of canceroustissues. Suitably engineered nanoparticles can deliver drugs, heat, light, and other materials only todiseased cells without damaging healthy tissues. In the field of electronics, lighter display screens have

been developed that consume less power, including flexible display panels made from nanowires.High density memory chips and much smaller transistors used in integrated circuits are beingdeveloped so that much smaller and more efficient computers can be produced. The market size ofnanoelectronics is presently estimated to be above $4 trillion.

In food science, nanotechnology is finding applications on improved methods to grow and store food.Silver nanoparticles have been incorporated in plastic storage bins so that harmful bacteria are killedon contact. Zinc oxide nanoparticles incorporated into packaging plastic films block UV light, and

provide anti-bacterial protection while making the films stronger and increasing their stability.Pesticides incorporated in nanocapsules release the toxic materials only in the stomach of insects thatconsume them, thereby protecting the plants (and us) from their harmful effects.

Nanosensors are being developed that recognise when individual plants need water, fertilizers ornutrients and trigger their release as and when needed, thereby optimizing the growth of each plant

and reducing the consumption of water, nutrients and fertilizers. Nanofood products are estimated tohave a market size of about $20 billion.

Other applications of nanotechnology include the development of bulletproof paper made fromnanocellulose which is stronger than steel, new light weight and stronger materials used in space craftand aeroplanes, and longer lasting light weight batteries. Nanotechnology has also been used for theeconomical production of stronger light weight textiles, tennis racquets and other sports goods.Textiles using nanotechnology are estimated to have a market size of $115 billion.
