Chip Sniffs Out Cocaine

Image
Effective and Inexpensive Chemical Sensor Chip It's a low cost chemical sensing chip that's as quick as a breathalyzer for alcohol to detect drugs. It's been developed by researchers at the University of Buffalo.  It's something that's long been on the wish list of law enforcement agencies to stop dangerous driving. It's spot-on for cocaine by simply sniffing it out within minutes. Ready and Portable  The chip can be packed into a portable, hand-held device that could test people real-time thru breath, blood, saliva or urine.  The chip gives results within minutes.  There's a great deal of demand for this kind of technology from police departments globally. Low-Cost and Effective According to researchers, the chip tests can be produced from raw materials costing 10 cents and the fabrication techniques are also inexpensive.  They hope to expand the test to drugs beyond cocaine such as opioids and marijuana. Nanotech The new test is an engineered...

Artificial Red Blood Cells - Washington University School of Medicine Innovation Life Saver From artificial hearts to prosthetic limbs, we've managed to replace many parts of the human body.  But blood seemed beyond our reach.  Now at Washington University School of Medicine in St. Louis, Allan Doctor, MD is developing artificial red blood cells.  They will serve as a blood substitute and bridging therapy that might keep severely injured people alive until they get to a hospital. Trauma Trauma is the leading cause of death in the US for those under 46 years old.  About 30,000 of those deaths could be prevented in those patients with severe bleeding from trauma. Nanotech Blood The Washington University research team is developing a freeze-dried, powdered blood substitute.  It's called ErythroMer and it's comprised of nano-scale, synthetic red blood cells that can deliver oxygen throughout the body. Time and Life Saving Medical Innovation F...

Electric-free, Self-Powered Smart Sensors

Self-Sustaining Smart Sensor Source:  NEU's Smart Sensor Detecting Air Pollution thru Infrared Wavelengths Zero Power Sensors Imaging a sensor that can lie on standby for years until triggered by infrared wavelengths, which it is built to detect. It could be used for detecting burglars, security threats, mobility, fire, fuel burning cars and much more.  Thanks to researchers at Northeastern University (NEU) in Boston, the next generation smart sensor uses the infrared wavelengths it is programmed to detect to power itself.  It's self-sustaining technological innovation that's green and environmentally clean.  NEU researchers have developed it for the US Defense Department's Advanced Research Projects Agency DARPA.  They call it "Zero-Power Sensors". Detecting What's Not Visible The infrared light waves the sensor detects aren't visible to the human eye.  And, they are abundant from, for example people, fires, emissions and cars.  They're e...
