Samsung biological analysis patent app has your best heart at interest
In Patent-application-land, the hills roll on forever, while buttercups gently ripple with the breeze. Anything is possible in Patent-application-land. In this particular filling, Samsung lays out some ideas about helping you to keep your health in check. An "internet phone" and a "biological analysis device" would combine to send your vitals off to a diagnosis server, hospital or remote doctor. There's also a provision for the use of "biochips," which we hope refers to a data gathering medium, and not a half-time snack. While we're not sure if this was a precursor to the freshly announced S-health service, if this ever came to be, at least you wouldn't need to leave the house to get that agoraphobia diagnosis.
Scientists separate plasma from blood with working biochip
Disposable biotech sensors won't let you diagnose your own diseases quite yet, but we've taken the first step -- a research team spanning three universities has successfully prototyped a lab-on-a-chip. Called the Self-powered Integrated Microfluidic Blood Analysis System (or SIMBAS for short, thankfully), the device takes a single drop of blood and separates the cells from the plasma. There's no electricity, mechanics or chemical reactions needed here, just the work of gravity to pull the fluid through the tiny trenches and grooves, and it can take as little as ten minutes to produce a useful result. It's just the first of a projected series of devices to make malady detection fast, affordable and portable. Diagram after the break!
Scientists create sweat-monitoring underwear, break them in (video)
Biochip bracelets be damned -- nanoengineers at UC San Diego want to put sensors in your skivvies. Researchers have begun prototyping a pair of tighty-whiteys coated with the requisite carbon electrodes to make electrochemical computing a reality, as it turns out the nether regions are a prime place to measure chemicals excreted in one's sweat. Until recently, there was some question whether the enzyme sensor solution would handle the stresses of daily life, so to speak, but these briefs were up to the task -- subjected to a torturous gauntlet of bending and stretching, a treated elastic waistband was still able to adequately measure chemicals as required. Funded by the U.S. Office of Naval Research, project leaders envision "smart underwear" that measures a soldier's sweat for warning signs and automatically trigger an appropriate medical dosage. We think they might be getting a wee bit ahead of themselves, though -- we don't yet know how they handle detergent, let alone a quality color-safe bleach. Video after the break, but don't expect any footage of the underpants actually being worn.
German researchers develop biotech sensor bracelet, disposable blood lab
Biochips -- flexible, disposable plastic circuits that "compute" via chemical reaction -- have been nearing reality for over a decade, but for obvious reasons we don't always pay attention. German research institute Fraunhofer IZM has just convinced us it's high time we did. This week, the organization announced that it's on the verge of creating a lab-on-a-chip that can diagnose deep vein thrombosis from a single drop of blood, as well as a wristband that can measure body temperature, skin moisture and electromagnetic radiation using plastic chips and sensors only micrometers thick. Impressive, yes, but the real news is the production process -- these gadgets can be printed in reels and sheets. The organization imagines the tools will be so cheap they'll be disposable; rather than wait for lab results, worried individuals will just take one out, test and toss to feel confident about their bloodwork, before hopefully going back to their normal lives.
NTT DoCoMo hopes to diagnose disease, predict other misfortunes from cellphones
We like to think that NTT, Japan's dominant telephone company, is a serious corporation. So when NTT DoCoMo issues a press release claiming to have successfully demonstrated the world's first "molecular delivery system for molecular communication," we figure this must be significant. The technology and biochemistry at the foundation sure seems to be. In an experiment, NTT DoCoMo confirmed the use of synthesized DNA to transport specific molecules through the body. The process converts chemical energy into mechanical work so there's no need for an external power supply or control mechanism. The hope then is to one day plant a "biochip" in a cellphone which can read "excitement, emotion, stress or disease" from the simmering juices (blood, sweat and tears) pooled inside the meatsicles of "living organisms." This is where things start to fall apart. Seeing as how this is Japan, that ambiguous target audience means you and your pets. Robots too, just as soon as they get skin. And when the English press release claims that a bio-chipped phone could be applicable to "fortune telling" -- well, we've lost all hope.[Thanks, StopSpamming]
