摘要：
Lateral diffusion of photon-generated carriers is a critical factor affecting the signal stability and spatial resolution of light-addressable potentiometric sensor (LAPS) array. LAPS with meshed working electrode for rejecting lateral diffusion is presented. Simulation shows that using meshed working electrode can resist the lateral distribution. In an experiment, the inhibition of lateral distribution and the signal stability was studied. Results showed, using the meshed working electrode, the ability to reject the lateral distribution and the signal stability is obviously enhanced. Research in this paper may help to enhance spatial resolution and detection stability of LAPS. (C) 2016 Society of Photo- Optical Instrumentation Engineers (SPIE)
