Sporty nano in Vancouver, Canada

As soon as I saw the title I knew it had to be a nanotech product. “The new ‘no sweat’ science” was an article in the Sunday (Dec. 21, 2008) edition of The Province daily paper. A local company, Firstar Sports (based in Surrey), makes a shirt that wicks away your sweat and never smells. The current CEO, Keith Gracey, wore the shirt over a period of months for his workouts and never washed it. Plus, he never had any complaints about the smell.

The ‘no smell’ part was the clue. There’s been a lot of talk about silver nanoparticles and their anti-bacterial properties which can be used in bandages to combat (infection and in clothing to combat smell.¬† Interestingly, nobody used the word nanotechnology or any of its variants in the article,

Throw in some anti-bacterial silver ions and Firstar’s garments have a 99.9-er-cent kill rate for bacteria after 50 washes, Gracey¬† (CEO) and Thom (Founder and VP) say. [emphasis is mine]

Certainly the marketing and PR folks seem to be backing off from using the nanotechnology or any of its variants. I commented on this development in my Talking nano posting. I also gave a link to an article by Alex Shmidt about this.

The article in The Province did not mention any risks but i don’t expect the reporter knew enough to ask the question. For the record, I have seen material which indicates that the silver nanoparticles (or ions) wash off, which means they could end up in our water supply. As far as I know, there’s no definitive data whether or not this feature could pose risks.
