The ability to extractย DNA from cells is a cornerstone of molecular biology. Without the ability to isolate pure DNA, there is no ability to sequence, cloneย or manipulateย that DNA.

Now, there is an even faster method developed for DNA and RNA isolation, and it takes about 30 seconds. The method uses revolutionary โdipstickโ technology. The protocol (if it can even be called that) is shown below.ย ย In it, a tissue sample is ground up and the dipstick (made ofย wax-coated filter paper) is placed into it, almost immediately capturing the DNA and RNA. Impurities can be washed away while the DNA and RNA stay attached to the paper which can then be transferred to the next step.
Even more remarkable, the new technique can isolate DNA fromย plants, animals, and microbes and veryย challenging biological samples such as blood and leaves from adult trees.ย This new method is cheaper (estimated at roughly $0.15 per sample), faster and easier than anything else available. Also, it does not require any accessory lab machinery such as a centrifuge or pipettes.

In essence, this will not only give researchers in labs around the world more time and money for more complicated experimentation, it will also take down the wall that exists between the lab and the rest of the world.
