(Innovation) This Tiny, Inexpensive Microchip Can Diagnose Diabetes Instantaneously

Stanford researchers recently published work on a small microchip they've developed that scans for diabetes in a fraction of the time of current tests. Additionally, their test is reusable for upwards of 15 patients, can be performed on site, and is more accurate in differentiating the biomarkers that distinguish type 1 and type 2 diabetes. In other words, it's a major milestone in diabetes research.

The chip itself only costs about $20 and is roughly the size of a glass slide. Its foundation lies on "an array of nanoparticle-sized islands of gold, which intensify the fluorescent signal, enabling reliable antibody detection." Auto-antibodies, which are responsible for attacking the healthy tissues that produce insulin, are found in type 1 diabetes but not in type 2. With a highly sensitive fluorescent detector, these antibodies are much more apparent and easier to recognize.

Patients are often misdiagnosed when it comes to diabetes, especially when currently there is no standardized testing method but rather a flurry of tests that can produce varying and sometimes contradictory results. Patients can also use the new microchip to track their auto-antibody levels before symptoms even begin, thus eradicating late-onset diabetes.

A test with immediate results is not only desirable to those at risk of both type 1 and type 2 diabetes, but also for developing nations whose labs and screening centers are underfunded and ill-equipped for diagnosis. Stanford's development team has applied for a patent and is currently seeking approval from the FDA. They hope to debut the technology soon. [via MIT Technology Review]

(Innovation) Google strikes smart contact lens deal to track diabetes and cure farsightedness

With Glass and Android Wear, Google has already invested a lot of time and resources into developing the next-generation of wearables, but it's another of its eye-focused projects that has today received its first major boost. The search giant's secret Google[x] team has confirmed that it's licensed its smart eyewear to healthcare specialist Novartis, which will develop the technology into a product that can improve eye care and help manage diseases and conditions.
As part of the agreement, Google[x] and Novartis' eye care division Alcon will create smart lenses that feature "non-invasive sensors, microchips and other miniaturized electronics" and focus on two main areas. The first will provide a way for diabetic patients to keep on top of their glucose levels by measuring the sugar levels in their tear fluid, feeding the data back to a smartphone or tablet. The second solution aims to help restore the eye's natural focus on near objects, restoring clear vision to those who are only farsighted (presbyopia).
Google's role will be to develop the tiny electronics needed to collect data and will also take care of the low-power chip designs and fabrication. Alcon, on the other hand, will apply its medical knowledge to develop commercial versions of the smart contact lens. "Our dream is to use the latest technology in the miniaturization of electronics to help improve the quality of life for millions of people," says Google co-founder Sergey Brin. "We are very excited to work with Novartis to make this dream come true."
