NANOTECHNOLOGY has revolutionised industry. It is used to improve wide ranging products, from cosmetics, toys and toothpastes to textiles and missiles. Industry thinks the technology holds promise to change every facet of life in some way. Substances at nano scale, or nanoparticles, demonstrate novel physiochemical properties compared to larger particles …
IT’S been a couple of years since scientists proposed that graphene, the new rockstar of the nano-world, is capable of revolutionising the healthcare sector. The one-atom-thick sheet of carbon can be used as an efficient vehicle to deliver drugs precisely to the target tumour or cancer cells. Its intrinsic optical …
THE recent accident at the Fukushima nuclear plant in Japan has left governments across the world worried over the safety of nuclear energy and its waste. As radioactive materials contaminated water, soil and air, technology to clean up the waste came to the forefront. Traditionally, naturally occurring substances such as …
IMAGINE a future when magnetic particles less than 100 nanometers in diameter will target, detect and capture images of cancer cells in your body. A team from the Indian Institute of Technology (IIT), Kharagpur, thinks such a future is possible. Researchers designed nanoparticles that can be used to transport drug …
FROM sunscreens, antiseptics to medicines that fight HIV, artificially engineered nanoparticles are vital for numerous consumer and industrial products. Of a nanometre’s size, these particles are of silver, gold, titanium dioxide and other elements and compounds. While nanotechnology has become the latest buzzword in science, a group of scientists has …
