Silk-based functional inks put biosensor data on your fingertips

Although we've seen "bio-inks" that allow sensors to be drawn directly on a person's skin and other surfaces to gauge things like glucose levels, functional inks such as this are usually heat-sensitive, meaning they aren't suitable for use in inkjet printers. Researchers at Tufts University have now developed silk-based inks containing bacteria-sensing agents that can withstand the rigors of inkjet printing, opening the door much wider for printing biomolecules.Read More

Toxin-detection system inspired by turkeys

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

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

iPhone biosensor does the work of a $50,000 lab-based machine

We already know that smartphones can perform many of the same features as more expensive computers, cameras and other devices. Now, a portable iPhone cradle made up of about US$200 worth of electronics is claimed to be as accurate of a biosensor as a $50,000 spectrophotometer that remains stuck in a lab. Read More

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

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.Read More

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

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.Read More
