Some biochips barely cover a human thumbnail, but they can hold over a half of a million samples of DNA.
And because this emerging technology offers a view of so many tiny bits of information at once, it's perfect for studying relationships among the 30,000 genes of the human genome, which are one of biology's next major mysteries.

trand lengths on the surface of the chip. These different segment lengths help scientists determine patterns among the strands. After researchers prepare the spotted array, they analyze legible pictures of it using computers.
The masks can take months to develop, and the test-tube samples require much work to prepare and store. For this reason, researchers worked with photo-chemistry to ......Full article >>>
proteins, and those proteins are the culprits," said Alex Vodenlich, CEO of GenTel.
For now, protein biochips remain in the shadows of established DNA research. The reason is simple: DNA has four base pairs that combine in a predictable and controllable way. Proteins, on the other hand, involve 20 amino acids and form an estimated 5 million shapes and sizes. Yet they cause action and reac......Full article >>>
