The future of glucose meters

This article is a review of the different technologies being developed to painlessly monitor glucose levels. Currently, the finger prick method is the most effective. Engineers have developed glucose meters which require less blood, but they would really like to eleminate the blood sampling process all together. One solution is a color changing contact lense that measures the glucose levels of tears. Gerard Cote here at Texas A&M is developing fluorescent beads that are injected under the skin. The beads will fluoresce different colors when exposed to light from an LED. The different colors would reveal the approximate glucose level. These are just a few of the many future technologies for glucose meters.
