Abstract

The light-addressable potentiometric sensor (LAPS) is capable to visualize chemical concentrations above the sensor structure, hence, generating chemical images. To read-out the sensors, a light pointer illuminates the sensor pixel-by-pixel and the resulting photocurrent will be determine. The lateral dimensions of a single pixel and the image resolution can be controlled by shaping the light pointer accordingly. This work demonstrates a flexible method to design on demand light pointers with different shapes and sizes, to carefully balance between measurement time and measurement resolution. This new method can provide large chemical images in a fast manner and provide high resolutions at required locations.
