Latest Patents

Weersink holds a patent for a method of measuring the concentration of luminescent materials in turbid media. This innovative method utilizes a fluorescence plus reflectance technique to quantitatively measure the in vivo concentration of a fluorescent drug, independent of the tissue's optical properties. The technique involves directing light to the tissue through an optical fiber to excite the fluorophores. Fluorescence is then measured by another fiber at a specified distance from the source, while the excitation light is simultaneously collected at a different distance. The ratio of fluorescence to reflectance remains approximately constant for a fixed concentration of the fluorophore, allowing for accurate estimations of concentration in turbid media.
