  • In the scope of miniaturized optical sensors for liquid refractometry, this work details the design, numerical simulation, and experimental characterization of a Fabry-PĂ©rot resonator consisting of two deeply-etched silicon cylindrical mirrors with a micro-tube in between holding the liquid analyte under study.

  • Refractometry is the analytical method of measuring substances' refractive index (one of their fundamental physical properties) in order to, for example, access their composition or purity. (wikipedia.org)
  • The latter method can achieve refractometry without the need for spectroscopy tools, provided certain criteria explained in the details are met. (mdpi.com)
  • The traditional method for measuring total protein uses the biuret reagent, but other chemical methods such as Kjeldahl method, dye-binding and refractometry are now available. (wikipedia.org)
