The name Jack Andraka is already one that researchers and medical practitioners are familiar with. Roughly a year ago, the 16-year old boy developed a litmus test that was capable of detecting pancreatic cancer, one of the most lethal forms of the disease and one of the most difficult to treat. And given that his method was 90% accurate, 168 times faster than current tests and 1/26,000th the cost, it’s title wonder why he’s considered something of a wonder kid.
Well, it seems boy genius is at it again! Shortly after receiving first place at the 2012 Intel International Science and Engineering Fair (ISEF), Andraka assembled a crack team of young scientists and began working on a handheld, non-invasive device that could help detect cancer early on. Much like Scanadu, the company that recently release a sensor for testing vitals, Andraka and his team were looking to create a genuine tricorder-like device.
And while their group – known as Generation Z and which was formed from the other 2012 finalists – is working towards such a device, Andraka presented his own concept at this year’s ISEF. Apparently, what he built is modeled on a tradition raman spectrometer – a device that can be used to detect explosives, environmental contaminants, and cancer in the human body.
A conventional raman spectrometer is extremely delicate, can be as large as a small car, and cost up to $100,000. By contrast, the one designed by Andraka costs only $15 and is the size of a cell phone. According to Andraka, a raman spectrometer works by “[shooting] a powerful laser at a sample and tells the exact chemical composition.” Such a device also relies on a liquid nitrogen cooled photodector to examine the chemical composition of whatever material is currently being examined.
Those powerful lasers alone can cost up to $40,000, so Andraka swapped out the big lasers for an off-the-shelf laser pointer and replaced the photodetector with an iPhone camera. According to Andraka, the results are comparable, at a fraction of the size and, more importantly, the cost. So once more, the boy genius has presented medical science with a cheap, effective means of early detection, something which could save lives and millions in health care costs.
Andraka admits that this device was pretty much all his, but he plans to incorporate it into the tricorder design that he and his colleagues in Generation Z are developing. Once realized, the resulting device will be competing for the Tricorder X Prize – a ten million dollar grant that is given to any entrant that can create a handheld mobile platform that can diagnose 15 diseases across 30 patients in just three days.
But of course, they will have some stiff competition, not the least of which will come from Scanadu, which just happens to have the backing of NASA’s Ames Center. But then again, the world loves an underdog. And when it comes to medical devices, cancer, and other diseases of the body, its clear that Andraka and his peers are just getting started!
