HeiQ
Swiss textiles maker HeiQ is marketing textiles featuring nanosilver as an antibacterial agent. The company is waiting for EPA approval of its AGS-20 agent.
The U.S. Environmental Protection Agency is reviewing public comments on a proposal to give conditional approval to a nanosilver product, but there’s no word yet on when a final decision might come down.

Wisconsin Assemblywoman Terese Berceau
When Wisconsin lawmaker Terese Berceau first learned about nanomaterials a few years ago, she found there were many nano-based products on the market, but little research into their possible health effects. “The horse was already out of the barn,” she said, but she found it hard to get anyone interested. “It is a difficult subject to get people feeling that, ‘Geez, we should do something now.’ ”

You may already be carrying quantum dots, carbon nanotubes and nano-silver around in your pocket: They’re all around us, part of a new industrial revolution that feeds a market for products like cell phones and bug-repellent clothing that could reach $2.6 trillion worldwide by 2015.
The federal government is trying to drive this runaway train with one hand on the throttle and another on the brakes. One agency is calling for a greater push to get nano-based products to market, while another says the government needs to put more emphasis on developing health and environmental standards.

Chicago — Food companies are working on ways to concoct a fluid that acts like oil but is made of water, and a food coating that changes color in the presence of E. Coli bacteria. But without a definition of “nanotechnology” from the federal Food and Drug Administration (FDA), we may not be frying potatoes in water anytime soon.

Nanotechnology may be an “emerging” science, but we’re already slathering its products on our skin, wearing them to go hiking and ingesting them in medicines and food. With more than 1,000 consumer items using nanomaterials already out there, a new California study urges government to take action to find out which ones might be dangerous and start getting them under control.

A Connecticut company that makes a line of what it labels “green” products for auto and marine use says it has just the thing for cleaning up the Gulf oil spill: A nanotech-based, biodegradable oil dispersant.
But a number of scientists and environmental groups are warning that the firm’s marine oil dispersant relies on nanoparticles in an untested formulation that could cause more harm than good.

DENVER – The red-hot nanotechnology industry — the development of super-products from tiny particles with surprisingly powerful properties—gets a fair amount of grief from environmentalists concerned about its environmental health and safety.
Yet at a time when the Gulf oil spill has revived pressure for “clean energy,” nanotech might also be generating some of the most promising hopes for jump-starting fossil-fuel alternatives like improved electric-car batteries and energy-efficient tires —if their inventors can find funding in new capital “valleys of death.”

“Buckyballs” could help halt the spread of cancer cells. They could help treat Alzheimer’s.
They could also potentially cause human cells to lapse into a comatose state.
All that from a “nanoparticle” far too small to see.
