George Orwell couldn’t have dreamed this up; from IT Pro:
IBM said that experts from nanofabrication, microelectronics, physics and biology are working together to master a technique where a long DNA molecule passes through a three nanometer wide hole (a nanopore).
As the molecule passes through the nanopore one unit of DNA at a time, an electrical sensor can ‘read’ 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.
