(March 2, 2015) A new simple tool developed by
nanoengineers at the University of
California, 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 from the University of
California, San Diego, 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 to draw sensors to measure glucose directly on the skin and
sensors to measure pollution on leaves.
