Nanosensors being developed by California Institute of Technology researchers will simultaneously look for thousands of different biomolecules and could be the basis for more accurate, cheaper, and more convenient cancer tests.
To turn a nanowire into a transistor, the researchers bring each of its ends into contact with metal wires so that a current can be passed through it. They then position an electrode close to the nanowire. Charging… read more
