A new simple tool developed by nanoengineers at the UC San Diego is opening the door to an era when anyone will be able to build sensors, anywhere, including physicians in the clinic, patients in their home and soldiers in the field. The team developed high-tech bio-inks that react with several chemicals, including glucose. They filled off-the-shelf ballpoint pens with the inks and were able … Continue reading New bio-ink pens allow users to draw glucose sensors on themselves, test for pollutants.
