Web1 day ago · A urine refractometer measures the refractive index of the urine. Its principle is that the refractive index compares the velocity of the light in air with the velocity of light in a solution. The dissolved particle concentration in the solution will determine the velocity and angle at which the light will pass through the solution. WebThe present study introduces a highly sensitive bimetallic SPR biosensor based on metal nitride for efficient urine glucose detection. Using a BK-7 prism, Au (25 nm), Ag (25nm), AlN (15 nm), and a biosample (urine) layer, the proposed sensor comprises of five layers. The selection of the sequence and dimensions of both metal layers is based on ...
