Sugar dip

Diabetics could soon buy a small urine analyser that measures their glucose
levels accurately enough to make regular trips to hospital unnecessary. The
pen-shaped sensor, from NEC, is far more accurate than the crude paper “litmus”
tests many diabetics use at home. NEC’s sensor uses a fluoride resin to remove
other chemicals. Enzymes in the sensor then react with sugar to produce an
electric current that can be read. NEC says its £150 device is almost as
accurate as standard £15 000 hospital-based machines.
