Elastic Drug Delivery Technology Releases Drugs When Stretched
Elastic Drug Delivery Technology Releases Drugs When Stretched
Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have developed a drug delivery technology that consists of an elastic patch that can be applied to the skin and will release drugs whenever the patch is stretched.
For example, if applied to the elbow, the patch would release a drug when the elbow bends and stretches the patch.

Smell, part four: Perfume Strips and Scratch 'n' Sniff

One of our first really popular posts on That's Not Online! was this one about old magazine and journal advertisements falling victim to digitisation. For the fourth installment of our series on smell (brought to you by watchful reader Vassiliki Veros), I would like to call your attention to two more casualties of the decline of print journalism: perfume samples and scratch and sniff technology.
According to Answers.com, the technology behind Scratch 'n' Sniff was invented in 1965 by an organic chemist working for 3M who was trying to make carbonless paper. The chemist, Gale Matson, succeeded in his goal, but the marketing department at 3M was tasked with coming up for some alternate uses for the patented micro-encapsulation technology, and Scratch 'n' Sniff was born. See HowStuffWorks for a more detailed explanation of the science behind this. Pull-apart perfume strips, another 3M brainchild, followed in either 1981 (as per Answers.com) or 1984 (says The New York Review of Magazines).
Scratch and sniff in popular culture, from Wikipedia's entry on scratch and sniff, lists some unusual uses of scratch and sniff technology, such as scratch 'n' sniff inserts in video games or music albums, and the 1981 John Waters film Polyester, which was released with Odorama -- a card containing 10 scent samples to be scratched at intervals throughout the movie. The most popular use of scratch 'n' sniff technology was for scented stickers, though it would seem these are not produced as often as they once were and have in fact become a collector's item. Mad Magazine included scratch 'n' sniffs for many years (if they still do, please let us know).
Perfume samples are still being included in magazines, of course, and this recent Forbes article reports that the technology is now also used for household cleaning products, hygiene and health products, and medicines and other remedies. The catch? They're not available on the iPad edition.
