摘要
En 中文
Integrated optical sensor chips suitable for high-resolution pH measurements are presented. The pi-I-sensitive swelling of a polymer membrane is detected by refractometry using a compact multi-channel sensor module. The signal transduction is achieved by means of chirped grating couplers which allow simple yet high functionality sensor modules to be built. The experiments have been performed with high sensitivity replicated polycarbonate TiO2 waveguide sensor chips coated with an ultrathin photopatterned hydrogel membrane having functional groups which reversibly change from the neutral state to a charged state upon acidification. A resolution delta pH < + 1.1 x 10(-4) in terms of the pH (at pH 7.5) has been obtained in a dual-channel module with size 10 x 10 x 10 cm(3). (C) 1998 Elsevier Science S.A. All rights reserved.
