The recent killing of Osama bin Laden and the very rapid determination of his identity through DNA and other techniques has generated a great deal of discussion on just how fast DNA analyses can be done. The facts are that with good samples a DNA profile and its matching against a known profile can be done in a few hours, perhaps as little as two or three. But there’s new technology on the horizon that might reduce this time to less than an hour and, just as important, allow this testing to be done in the field by non-specially-trained individuals.
Network Biosystems (NetBio) is the creator of this portable instant DNA scanner that utilizes microfluidics, a rapidly expanding technology that makes use of very small volumes of liquids and microcapillary tubes. Since it is portable, rapid, and doesn’t require a scientifically-trained operator, it will no doubt prove to be a valuable forensic tool.
Lab on a Chip (LOCAD)
I first learned about this technology a couple years ago when I spent time with Dr. Lisa Monaco at NASA’s Marshall Space Flight Center in Huntsville, AL. She explained the microfluidic technology she employs in her Lab-on-a-chip (LOCAD) research and indeed one of her devices is currently roaming around Mars, seeking evidence of nitrogen, oxygen, water, and other chemicals, as well as the amino acids required for life.

Whether on the surface of Mars or at a crime scene, this technology has a bright future and I suspect we will see an increasing number of uses for it.
