Abstract

Tilted Bragg Grating (TFBG) sensors for determining the total cholesterol have been designed and developed. TFBG sensors have the advantage of intensity measurements rather than wavelength modulation. A biopolymeric thin layer of chitosan was coated over the TFBG in order to enhance the sensitivity. The developed sensor heads showed good stability and repeatable performance. The sensor also showed good linear response in the measured range cholesterol levels.
