Cheap as Chips
Behold: the first ever (working) capillary gel electrophoresis chip made using high-definition inkjet 3D printing. The chip, produced by a team from the Wrocław University of Science and Technology, is capable of separating a 50–800 bp DNA ladder, and its transparency allows it to be used for laser-induced fluorescence detection. While less sensitive than those made with conventional fabrication techniques, the chip is up to 40 times cheaper, and takes hours – rather than days – to produce.
