    Abstract: A live biological specimen is imaged by generating a plurality of light sheets; directing the plurality of light sheets along an illumination axis through the biological specimen such that the light sheets spatially and temporally overlap within the biological specimen along an image plane, and optically interact with the biological specimen within the image plane; and recording, at each of a plurality of views, images of the fluorescence emitted along a detection axis from the biological specimen due to the optical interaction between the light sheets and the biological specimen. The temporal overlap is within a time shift that is less than a resolution time that corresponds to a spatial resolution limit of the microscope.

    Abstract: The present invention relates a method to determine the presence of a photon producing biological marker in a cell, tissue or organism of interest. The method is based on Fluorescence by Unbound Excitation from Luminescence (FUEL) and comprises the steps of a) providing conditions suitable for the biological marker to produce at least one first photon by luminescence; b) providing a FUEL probe pair-upper (FPP-U) disposed in proximity to the cell, tissue or organism, wherein the at least one first photon of step a) excites the FPP-U, which emits at least one second photon. The FPP-U may be selected from the group of quantum dots, carbon nanotubes, fluorescent proteins, diamond nanocrystals and metalloporphyrins. This method is characterized in that said biological marker and said FPP-U are not bound and in that each of the at least one second photon(s) are of a longer wavelength than each of the at least one first photon(s).

    Abstract: The invention relates to a light source for irradiating molecules present in a detection volume with one or more selected wavelengths of light and directing the fluorescence, absorbance, transmittance, scattering onto one or more detectors. Molecular interactions with the light allow for the identification and quantitation of participating chemical moieties in reactions utilizing physical or chemical tags, most typically fluorescent and chromophore labels. The invention can also use the light source to separately and simultaneously irradiate a plurality of capillaries or other flow confining structures with one or more selected wavelengths of light and separately and simultaneously detect fluorescence produced within the capillaries or other flow confining structures. In various embodiments, the flow confining structures can allow separation or transportation of molecules and include capillary, micro bore and milli bore flow systems. The capillaries are used to separate molecules that are chemically tagged with appropriate fluorescent or chromophore groups.

    Abstract: The present invention provides an optical oxygen concentration measurement method and optical oxygen concentration measuring sensor wherein a light-absorbing dye-molecule layer whose absorption spectrum varies depending on the bonding with oxygen molecules is combined with a light-emitting layer, and the oxygen concentration of the ambient fluid can be measured. The light-absorbing layer 4 laminated to an oxygen-quenching light-emitting layer 3 is a film comprising a cobalt-porphyrin complex (CoP) or other light-absorbing dye molecule 7 whose absorption spectrum varies depending on the bonding with oxygen molecules. When the degree of overlap with the light emission spectrum or excitation (absorption) spectrum of the light-emitting layer 3 varies as a result of a variation in the absorption spectrum possessed by the light-absorbing layer 4, the light intensity of output light varies in accordance with the degree of overlap, and the oxygen concentration of the ambient fluid can be measured. These measurement method and measuring sensor can be applied not only to optical fiber sensors, but also to wind tunnel experiments and the like as pressure-sensitive paints.

    Abstract: The Laser Induced Fluorescence Attenuation Spectroscopy (LIFAS) method and apparatus preferably include a source adapted to emit radiation that is directed at a sample volume in a sample to produce return light from the sample, such return light including modulated return light resulting from modulation by the sample, a first sensor, displaced by a first distance from the sample volume for monitoring the return light and generating a first signal indicative of the intensity of return light, a second sensor, displaced by a second distance from the sample volume, for monitoring the return light and generating a second signal indicative of the intensity of return light, and a processor associated with the first sensor and the second sensor and adapted to process the first and second signals so as to determine the modulation of the sample. The methods and devices of the inventions are particularly well-suited for determining the wavelength-dependent attenuation of a sample and using the attenuation to restore the intrinsic laser induced fluorescence of the sample. In turn, the attenuation and intrinsic laser induced fluorescence can be used to determined a characteristic of interest, such as the ischemic or hypoxic condition of biological tissue.
