Abstract
An optical fiber sensor for albumin detection has been fabricated and teste d. The adsorption Langmuir-Blodgett (LB) method was employed to form organi c thin films on the optical fiber. The spectral change can be monitored by the interaction between the evanescent light from the fiber core and the ad sorption LB films. A relatively high sensitivity and linear relationship be tween the spectral change and the albumin concentration were obtained. (C) 2000 Elsevier Science S.A. All rights reserved.
