Researchers from Cornell University have developed a miniaturized DNA-based biological testing system that fits on a silicon chip and can be customized to detect a wide variety of microorganisms.
The 2 cm x 4 cm chip captures the DNA from the sample and purifies it. A reaction chamber performs a polymerase chain reaction to rapidly replicate the selected segment of DNA, which can then be tested.
Cady and… read more
