Don't forget to write! Electrochemical charge storage in a ruthenium-based monolayer on a hydrophilic substrate (for example, indium tin oxide coated glass) produces redox switching of the optical properties of the system (see picture). This read/write process can be carried out at low voltage in air and monitored by UV/Vis spectrophotometry. This makes the monolayer system a suitable candidate for nonvolatile memory devices.
