A Long Period Grating based biosensor for the detection and estimation of cholesterol

摘要

A Fiber Optic sensor for the detection and estimation total cholesterol has been designed and developed. The Long Period Grating (LPG) sensor developed showed a linear response in the range of 500ppm to 4000ppm of cholesterol levels. This is highly desirable for a commercial cholesterol sensor as the level of cholesterol for normal humans ranges from 1400ppm to 2000ppm.
