Latest Patents
Xin Su holds a patent for a method of evaluating pH using an inorganic-oxide nanoparticle-based optical pH sensor. This method involves the use of optically active nanoparticles fixed to a substrate. These nanoparticles exhibit a localized refractive index modulation over a pH range from 2.0 to 12.0 of at least 1%. The average diameter of these nanoparticles is less than about 500 nanometers. The process includes contacting the pH sensing material with the aqueous solution, illuminating it, and monitoring the optical signal generated through the comparison of incident light and exiting light. This allows for the determination of the optical transmission, absorption, reflection, and/or scattering of the pH-sensitive material. The optical signal varies in response to the pH of the solution, providing a reliable means to analyze pH levels and any changes.
