A method of measuring an analyte present in animal (e.g., human) tissue or fluids such as blood or plasma. The analyte is multi-photon excitable (e.g., two-photon excitable) at a first wavelength at which the animal tissue is substantially non-absorbing. The analyte fluoresces at a second wavelength...http://www.google.fr/patents/US5759767?utm_source=gb-gplus-shareBrevet US5759767 - Two-photon and multi-photon measurement of analytes in animal and human tissues and fluids
