To find Kim Hyung Gyoon’s office in Samsung’s R&D complex,iust follow the baskets of dirty clothes.No, Kim is not running the company laundry.As chief of Samsung’s Washing & Cleaning Technology Group(WCTG),he’s the man behind a new washing machine that deposits tiny silver particles(small pieces of things)-about 1/10,000 the thickness of a human hair—onto clothes to make them germ-and-odor- free without the need for hot water.The device represents the first mass-produced application of this type of nanotechnology—the science of very small structures—to home appliances."In summer of 2002, I asked everyone in the office to take off their socks,"says Kim."I took one sock from each person and placed it in a regular washing machine; the others were washed in a machine with the Ag + Nano System.The next day, I asked everyone to check the odor of their socks after a day’s wear.One began to produce a strong unpleasant smell, and the other was odorless."
Kim says he came up with the idea five years ago while on a business trip to Japan, where he learned of a brand of socks that retained their freshness even after many days of unwashed wear and tear.Tiny sticks of silver with germ-killing chemicals were woven into fabric.When he got back to Seoul, Kim applied the principle to washing machines.
According to the Korea Testing & Research Institute for the Chemical Industry, Samsung’s device killed 99.9% of germs.Kim says garments stay germ-free for up to a month after being laundered.The Ag + Nano device went on sale in March 2003 and costs around $1,150; the revolutionary technology is also being used in Samsung’s refrigerators and air conditioners.
No wonder: consumers seem to like a little silver in their spin cycles.Since Samsung’s nano-armed products were first launched, they have brought in an estimated $779 million in revenue.Overall, nanotech has been one of science’s fastest- growing fields in recent years, with potential applications in fields as diverse as energy production and toothpaste manufacture.The nanotech market is projected to be worth $1 trillion by 2015.
The author believes that the future of nanotechnology will be______.
