    Abstract: A particulate detector (10) comprises a radiation source (12) arranged to emit radiation in at least first and second predetermined wavebands towards a sampling region (18) suspected of containing particulates, and a detection element (14), shielded from the radiation source (12), and arranged to detect radiation from the sampling region (18) at least first and second instances. The radiation source (12) is such that the emissions in the wavebands temporarily overlap. The detector is such that, at the instances at which the radiation is detected, the relative contributions from the emissions in each predetermined waveband are distinguishable, thereby allowing characteristics of the particulates to be determined. The radiation source (12) may comprise a light emitting diode (24).

    Abstract: A method of producing a surface enhanced Raman scattering spectrum which is useful for certain types of assays, in particular proximity assays. The method includes providing two SERS-active nanoparticles. The first SERS-active nanoparticle will absorb a photon at a first wavelength and emit a Raman-shifted photon at a second wavelength. The second SERS-active nanoparticle will absorb a photon at the second wavelength and emit a Raman-shifted photon at a third wavelength. Accordingly, when the first and second SERS-active nanoparticles are proximate to one another and the first SERS-active nanoparticle is illuminated at the first wavelength a Raman-shifted photon at the second wavelength may be emitted. This photon can be absorbed by the second SERS-active nanoparticle causing detectable emission of a second Raman-shifted photon at the third wavelength. Various assays may be designed based upon the above. Proximity assays using two SERS-active nanoparticles will have advantageous background signal characteristics.

    Abstract: The Laser Induced Fluorescence Attenuation Spectroscopy method and apparatus include a source (311) adapted to emit modulated radiation that is directed at a sample volume in a sample (314) to produce return light from the sample, a first sensor (321), 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 (322) 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 (323) adapted to process the first and second signals so as to determine the modulation of the sample. Methods and devices are well-suited for determining the wavelength-dependent attenuation of a sample and using the attenuation to restore the intrinsic laser induced fluorescence thereof, and can be used to determine the ischemic or hypoxic condition of biological tissue.

    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.

The 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 determine a characteristic of interest, such as the ischemic or hypoxic condition of biological tissue.
