Google Glass Might One Day Diagnose And Track Diseases Like HIV

When Google began releasing its new head-mounted computer to beta testers last year, technology enthusiasts were pumped. After all, the futuristic device, called Glass, might one day enable people to answer email hands-free or view driving directions projected onto the road in front of them. Others, though, have complained that Google Glass is a cool piece of tech that hasn’t yet justified its existence. (Still others have complained that Glass is creepy, but that’s a story for another day.) Slowly but surely, though, beta testers in Google’s Explorers program have been making a case for the sophisticated eyewear by demonstrating its unique—sometimes scientific--capabilities. Physics teacher Andrew Vanden Heuvel famously shared his visit to the Large Hadron Collider, in Switzerland, with his students via Glass. Ohio surgeon Christopher Kaeding gave medical students a live, bird’s eye view of a knee operation he conducted while wearing the device. And now, a research team led by Aydogan Ozcan of the University of California, Los Angeles, is using Google Glass to help diagnose and track disease. The engineers designed an app for the wearable computer that images and reads rapid diagnostic tests such as pregnancy pee sticks. It also links the results to a scannable QR code, stores them, and tags them geographically. “The new technology could enhance the tracking of dangerous diseases and improve response time in disaster-relief areas or quarantine zones where conventional medical tools are not available or feasible,” Ozcan says. Among the first to be selected by Google as Explorers, Ozcan and his team demonstrated the capabilities of their new app by using it to read a few types of home HIV and prostate cancer tests—ones that require an oral swab or a drop of blood to work. They recently published their efforts in ACS Nano (2014, DOI: 10.1021/nn500614k). True, it doesn’t take much to read one of these tests—either lines appear or they don’t in the case of the HIV tests. But the app could save time for clinicians who routinely have to read a multitude of different types of sticks and remember which symbols and lines signify a positive or negative result, Ozcan points out. After a single calibration run, the online tool recognizes a particular test stick and can even assign a biomarker concentration to the lines that appear. These rapid diagnostic tests typically use nanoparticles to create these lines (which is why Ozcan’s study appears in ACS Nano). Coated with an antibody, the particles recognize a specific biomarker in blood, urine, or saliva samples and bind to it. As the particle-biomarker complex flows down the test stick, rows of a different type of antibody already...

Guest Post: “Google Glass and Twitter for Chemistry Education” by Arash Soheili

Today’s guest post is from Arash Soheili, a postdoctoral researcher at the University of Texas, Southwestern Medical Center. As curator of the Twitter account @Total_Synthesis, which is turning 2 this month, no new total synthesis in the journals escapes his watchful eye. He’s passionate about teaching chemistry. And we’re jealous of him because he got to visit Google’s NYC offices to pick up his very own Google Glass. Check out his tech musings at Android Cowboy. I love organic chemistry and have been practicing it in academia and industry for over a decade. I’m also a huge fan of technology and strongly believe that there is a place for it in chemistry education. In fact, I would even say that in the next decade it will become a necessity to incorporate technology as part of the formal teaching toolkit. That process is already happening informally with so many educational videos on YouTube from enthusiasts and educators. But so many technology tools are constantly changing and it will take a strong effort on educators to find the methods that work best. Just like running an experiment in the lab, it will take planning, as well as some trial and error, to get the best results. My personal experience with chemistry and education started about two years ago. I wanted to find a way to reach more people and introduce new and interesting topics in chemistry using existing social networks. My passion for natural product synthesis led me to start a total synthesis Twitter feed. I check all the major organic chemistry journals daily and tweet any completed total synthesis of a natural product that I find. If you are interested in natural product synthesis then you can easily follow the Twitter feed and be up to date. You can also join the conversation by using the hashtag #totalsynthesis. The idea was very simple, but it had yet to be executed. Now in two years there are close to 1000 followers and it serves as an archive of over 400 natural product syntheses in all the major journals. This information would be hard to collect and very laborious using the typical search methods like Google, ACS, SciFinder, etc. It is an idea that can be duplicated for any other topic of interest in science and can be even tried in a formal class setting. Similar ideas include the online Twitter #chemclub by Andrew Bissette. Social media tools are far from the only game in town. Hardware tools have huge potential for application in chemistry education. One example is Google Glass which is basically a head mounted computer with the ability to...
