Microfluidics Device for DNA Testing
Quoting directly: “The ‘Paper Machine,’ as the researchers behind the project call it, is a microfluidic device made out of paper that costs about two dollars to produce. Without much training, a user can use it to prepare the liquid sample, perform loop-mediated isothermal amplification (LAMP) and finally shine ultraviolet light and use a smartphone to detect the presence of nucleic acid sequences pointing to disease. The device has a central sliding plate that is pulled by the user one notch after each step in the four-step testing process. This essentially automates the process of adding the sample, introducing the wash buffers, then the amplification master mix, followed by a stain dye once incubation is complete. A simple blacklight can then be used to illuminate the resulting sample, with a smartphone camera then spotting the presence of the dye.” MORE
