IBM researchers are developing a chip for cheaper, faster DNA sequencing using fabrication techniques refined through semiconducting manufacturing.

The chip uses layered electrodes to control the movement of individual DNA molecules and exploits a technique called nanopore sequencing. The approach could allow DNA to be passed through a sensor that would rapidly read off its genetic code.
