Nanotech Dog Nose Sniffs Out Explosives, Illicit Substances

About a quarter century ago, Americans started bringing home smoke detectors from the local hardware store, placing them in areas all around their houses to protect life and property from fire. Later, carbon monoxide and radon detectors were added. Now, newly-developed detectors for explosives and illicit substances will become as commonplace, especially in public spaces and even on portable devices like smartphones.
To date, this type of work has been done by “sniffer” dogs whose olfactory cells absorb molecules that are undetectable to humans. In fact, dogs have long been considered by law enforcement as the “gold standard” in explosive and illicit substance detection according to Carl Meinhart, mechanical engineer, and Martin Moskovitis, chemist, at the Institute for Collaborative Biotechnologies at University of California, Santa Barbara (UCSB). The new portable, highly accurate, matchbook-sized device is based on the biological design in dog noses and uses microfluidics and nanotechnology to capture v***rs just as biological mechanisms in dog noses.
“A dog can have a good day or a bad day, get tired or distracted,” Meinhart says. “We have developed a device with the same or better sensitivity as a dog’s nose that feeds into a computer to report exactly what kind of molecule it’s detecting.”
Vapors are captured at “parts per billion” of explosives and other molecules in microscale channels. These substances bind to nanoparticles inside a chamber where a laser beam detects their presence and reads their spectral signature.

At the heart of the new device, like many current cutting edge technologies, is the marriage of disciplines, in this case, mechanical engineering and chemistry. An example of the device’s capabilities includes the capture of airborne molecules of 2,4-dinitrotoluene, a primary v***r signature of TNT based explosives. The device “sniffs” in real time and senses molecules below concentrations of 1 part per billion (PPB) or below. SpectraFluidics has licensed the patented technology and will bring it to market over the next several years.

Shape-Shifting Wheel Rolls Over Any Terrain

Traveling across different countries in Africa has many obstacles, namely the lack of infrastructure in remote areas where vehicles can’t cross the terrain. It’s with the context of Nkhata-Bay in Malawi in mind that engineering student Ackeem Ngwenya has devised the Roadless, a shape-shifting wheel that can adapt to different surfaces.
Ackeem was anxious to bring his design to a wider audience while also raising money to pay for his tuition so he could graduate. His IndieGoGo campaign, unfortunately, failed in reaching its goal.
But Ackeem’s work may not be in vain. He’s supported by the James Dyson Foundation so the project may not yet be at death’s door.
The Roadless works off the principles of a scissor jack mechanism. As the hub is cranked down it creates a wider wheel when necessary or can contract to a slimmer model; all depending on the terrain you are trying to cross. The wheels can be fitted onto an axle for transportation.
In muddy and soft ground, the wider wheel is used and for a hard, bumpy and rocky surface, the thinner set is applicable. This doesn’t limit the user to just two settings, though, as the Roadless can be adjusted a middle size and width too.

About 85% of the Malawi population lives in rural areas and Ackeem grew up in one of these areas, bearing witness to the transportation issues and the hardships it brought in moving goods. Nearly the entire country lives off farming and once they have harvested enough food to feed their families, many people look to sell their surplus to make a living. However, the marketplaces are often far out of the way and transporting the goods is arduous. This is what Roadless aims to solve as, realistically speaking, infrastructural investment in countries like Malawi is not on the horizon.
“I grew up in Mlore, a remote village in Malawi, an area with no transport infrastructure or service,” says Ackeem. “It was and still is not unusual for people to head-load goods in excess of 25kg for more than 10km. In fact, this is the load and journey my cousins and I took to mill corn when I was about 10.
“With Roadless I can do something about these conditions and contribute towards its development.”
He has developed a number of prototypes so far and tested his designs with a tire as well to examine its feasibility in moving between sizes. The project was just over £5,000 funded, with a goal of £25,000 but sadly did not make its goal in time. You can still view the IndieGoGo campaign where Ackeem has posted a number of sketches and videos of his work.

A Brief History of Robots
A Brief History of Robots - Honda Collection (Image Courtesy www.honda.com) - http://d3z1rkrtcvm2b.cloudfront.net/…/Honda_prototype_robot…
Since Karel Capek first introduced the world to robots in his 1920 Czech play, R.U.R.: Rossum’s Universal Robots, people have been fascinated by robots (and slightly afraid that they might take over the world).
Thirty years later, American author Isaac Asimov began to popularize robots through his science fiction books including I, Robot and The Bicentennial Man. While actual working robots have a long way to go before they live up to their science fiction personas, many exciting advancements in robotic technology have been made. Here are some of my favorite moments in the brief history of robots.
The following “Brief History of Robots” timeline extends from 3000 BC to 2014 and includes:

3000 BC: Egyptian water clocks use human figurines to strike the hour bells
1495: Leonardo da Vinci sketches plans for a humaniod robot
1790: Industrial revolution introduces complex mechanics and electricity
Karel Cepek coins the term “robot”
