Scientists at Johannes Gutenberg University Mainz (JGU) in Germany have discovered that molybdenum trioxide nanoparticles oxidize sulfite to sulfate in liver…
The novel pH value sensor works according to an optical electrochemical principle and comprises a photoluminescent or fluorescent layer, a light source and a detector. The layer comprises an electric potential and acts as a working electrode which is implemented as a nanostructure (nanowires with quantum dots). Furthermore, spatial resolution can be achieved by using numerous nanowires contacted individually on a carrier and a visual array detector (analogous to CCD sensors in digital cameras).
Other reactions or concentrations of substances can also be detected.
