Laser Takes Needless Out Of Diabetes Test

Professor Joseph Chaiken, of the department of chemistry at Syracuse University has developed the LighTouch, which accurately monitors glucose levels without a single drop of blood.
The new procedure uses a laser to measure spectroscopic signals in blood while the blood is still in the capillaries, allowing abnormal levels of blood components like glucose to be detected without pricking a person's finger.
Chaiken's research involves using spectroscopy to gain a fundamental understanding of light and matter interactions, then applying that research to solve practical problems of importance.
