Toxin-detection system inspired by turkeys

By - January 22, 2014 2 Pictures
Turkeys may not be everyone's idea of beautiful birds, but they certainly have colorful skin on their heads. What's more, that skin changes color with the animal's mood. Scientists at the University of California, Berkeley, have now copied the process by which those color changes occur, and used it to create a biosensor that could be used to detect airborne toxins.

PLEASED project working on "plant-borgs" to act as environmental biosensors

By - January 20, 2014 1 Picture
Many claim that talking to plants helps them grow faster. But what if the plants could talk back? That’s what the EU-funded PLants Employed As SEnsing Devices (PLEASED) project is hoping to achieve by creating plant cyborgs, or "plant-borgs." While this technology won't allow green thumbs to carry on a conversation with their plants, it will provide feedback on their environment by enabling the plants to act as biosensors. Read More

Cell-powered "bio-bots" get a wriggle on

By - November 17, 2012 1 Picture
Using a 3D printer, researchers at the University of Illinois have developed synthetic "bio-bots" about seven millimeters long that are powered by embedded cardiac cells that give them the ability to "walk" on their own. The researchers say they are just scratching the surface of what is possible, with their work potentially leading to millimeter-scale medical or environmental sensors that that can seek out and neutralize harmful toxins.

Tiny biosensor could mean an end to daily finger sticks for diabetics

By - September 7, 2012 1 Picture
Despite promising developments in recent years, millions of type-1 diabetes sufferers worldwide still face the often-painful daily burden of finger sticks to test their blood glucose levels. Now researchers at the Fraunhofer Institute for Microelectronic Circuits and Systems (IMS) have developed a biosensor that provides a non-invasive way to measure blood glucose levels and can transmit its readings wirelessly to a mobile device.

"Whispering gallery" biosensor detects the smallest viruses

By - August 28, 2012 2 Pictures
Researchers led by Professor Stephen Arnold at Polytechnic Institute of New York University have developed a new ultra-sensitive biosensor. Currently undergoing commercial development, the sensor is designed to inexpensively identify viruses in a doctor’s office within a matter of minutes instead of the weeks needed by conventional techniques ... and it can detect even the smallest RNA virus particle, MS2, which weighs only six attograms (10-18 grams).
