Making biochips, a key technology in studying disease, just got a little easier. This new nanoprinting process uses gold-plated pyramids, an LED light, and photochemical reactions to print more organic material on the surface of one single biochip than ever before. This nanoprinting process allows researchers to 3D print more material on a biochip than ever before, making it easier to study biomedical issues. This process likely known as tip-based lithography, are widely considered to be the best way to 3D print organic material with nanoscale feature resolution. They’re using microfluidics, the manipulation of fluids on a molecular level, to expose each biochip to the desired combination of chemicals.
