Implementation of porous silicon technology for flow-through sensing using electro-osmotic phenomenon
A demonstration of pH sensing for natural waters using nanoscaled porous media and electro-osmotic flow sampling has been performed. This paper presents an innovative integration of sensing and nano-scaled fluidic actuation in the combination of pH sensitive optical dye immobilization with the electro-osmotic phenomena in polar solvents like water. Through wafer nano-scaled porous silicon and porous silica membranes have been demonstrated as porous media and template for high density fluorescence measurements on optical dyes.
