In the second in our series of investigations into the lesser known R&D activities of beastly old Intel, we meet the man behind a revolutionary new bioelectric diagnostic chip.

Medical diagnostics is a pretty time consuming and expensive endeavour. Testing bodily fluids for various markers of ailments and disease, spooling up those high tech scanners... it all adds to the cost of health care. It's a cost that is becoming increasingly crippling in developed nations.

But what if there was a technology that was not only massively cheaper, but also much faster, as well as more sensitive and more capable? Well, there is.

At least that's what Ilan Levy, one of Intel's big brains at its research centre in Israel (yup, that'll be the same Israeli outfit that saved Intel's bacon with first, the Pentium M, and then, Core 2 CPU architectures).

The basic idea is simple enough to grasp. To use Intel's peerless silicon chip expertise to mass produce a computer chip festooned with diagnostic sensors. "We have developed a single-die chip with 148 different sensors capable of multiple levels of analysis," Levy explains.

A chip thats cheap

Thanks to the use of cutting-edge silicon technology, the final production chip is likely to be very small, and hence extremely cheap. That in turn should allow it to be integrated into a low cost, disposable, single-use cartridge that plugs into a larger reusable device.

For this usage model, bodily fluids are passed over the chip and the resulting signal or data is wirelessly sent to a control system. Simply replace the cartridge and repeat for each test subject.

In theory, the single chip Intel has developed is capable of performing any bodily-fluid based diagnostic currently available. That includes tests that require cultures to be grown.

Levy explains: "The standard method for detecting some infectious agents is to grow cultures. Take hepatitis. For that, it's important to know how many viral particles are present in one cc of blood."

Currently, the medical industry uses a molecular detection method, which is based on the DNA composition of the virus. The idea is to amplify the amount of genetic material to detect it. "But with our chip, using an electrical detection method, it is possible to detect a single virus."
