Does the InsiteIG fluorescence technology infringe on any U.S. patents?
Answers Q1.) How can dissolved oxygen be measured using fluorescence? BACK TO TOP A very specific energy wavelength is transmitted to a ruthenium compound immobilized in a sol-gel matrix. The ruthenium will absorb this energy, changing the outer electron’s energy level. The electron will then collapse back to it’s original energy state, emitting the energy as a photon with a different specific wavelength. This is called fluorescing. If the intensity of the transmitted wavelength is tightly controlled, the amount of fluorescing is both predictable and repeatable. If oxygen molecules are present the amount of fluorescing is reduced, referred to as fluorescence quenching. By measuring the amount of quenching it is possible to determine the amount of oxygen present. Q2.) How long has this technology been in use? BACK TO TOP Fluorescence technology has been used to measure oxygen uptake in the medical industry for over twenty years. Within the last five years the technology has been adapted
