A Diffusion-Based pH Regulator in Laminar Flows with Smartphone-Based Colorimetric Analysis
A strategy for an on-chip pH regulator is demonstrated computationally and experimentally, based on the diffusion characteristics of aqueous ionic solutions. Micro-flows with specific pH values are formed based on the diffusion behaviors of hydrogen and hydroxide ions in laminar flows. The final ach...
