Review on Hydrogel-based pH Sensors and Microsensors (2008, methodology): “In fluidics and microfluidics outstanding multi-purpose functionalities have been emerged involving microvalves [16-20], automatic valves [15,16,18, 21-24], pumps [25-27], and chemostat valves performing feedback control to keep an adjustable concentration on a constant level, e.”
Characterization of a microgravimetric sensor based on pH sensitive hydrogels (2004, background): “It could be shown, that the flow rate of a liquid through a hydrogel-based valve depends on the properties of the fluid, like pH, temperature, and concentration of organic compounds in water [20,21].”
