nk497 (1345219) writes "IBM scientists are working on ambitious research where nano-sized holes will be drilled into computer chips and DNA passed through to create a 'genetic code reader'. A DNA molecule would be passed through a hole just three nanometers wide, while an electrical sensor "reads" the DNA.
The challenge of the silicon-based 'DNA Transistor' would be to slow and control the motion of the DNA through the hole so the reader could decode what is inside it. IBM claimed that if the project was successful it could make personalised genome analysis as cheap as $100 to $1,000, and compared it to the first ever sequencing done for the Human Genome Project, which cost $3 billion."
