Four years ago, words like “impossible,” “futuristic,” and “science fiction” filled discussions about nanotechnology. Since the announcement of the US National Nanotechnology Initiative in 2000, though, worldwide investment in nano research and development has raced forward, with $8 billion invested in 2004 alone. That kind of growth has leaders at major companies sitting up and [...]
ano-this and nano-that. These days it seems you need the prefix “nano” for products or applications if you want to be either very trendy or incredibly scary. This “nanotrend” has assumed “mega” proportions: Patent offices around the world are swamped with nanotechnology-related applications; investment advisors compile nanotechnology stock indices and predict a coming boom in [...]
Truly revolutionary nanotechnology products, materials and applications, such as nanorobotics, are years in the future (some say only a few years; some say many years). What qualifies as “nanotechnology” today is basic research and development that is happening in laboratories all over the world. “Nanotechnology” products that are on the market today are mostly gradually [...]
One of the promises of medical nanotechnology is a drug-delivery nanodevice that can image, target, and deliver drugs to a specific cancer location inside the body and monitor and if necessary adjust the drug release at the target location. Researchers in Taiwan have now designed a nanodevice that comes pretty close to this vision. “We [...]
