Video: IBM DNA Transistor

In an effort to build a nanoscale DNA sequencer, IBM scientists are drilling nano-sized holes in computer-like chips and passing DNA strands through them in order to read the information contained within their genetic code.

This research effort is to design a silicon-based DNA Transistor that could help pave the way to easily and quickly read human DNA, generating advancements in health condition diagnosis and treatment. The challenge in the effort is to slow the flow of the DNA through the hole so the reader can accurately decode what is in the DNA.
