    Abstract: An apparatus and method are provided for differentiating multiple detectable signals by excitation wavelength. The apparatus can include a light source that can emit respective excitation light wavelengths or wavelength ranges towards a sample in a sample retaining region, for example, in a well. The sample can contain two or more detectable markers, for example, fluorescent dyes, each of which can be capable of generating increased detectable emissions when excited in the presence of a target component. The detectable markers can have excitation wavelength ranges and/or emission wavelength ranges that overlap with the ranges of the other detectable markers. A detector can be arranged for detecting an emission wavelength or wavelength range emitted from a first marker within the overlapping wavelength range of at least one of the other markers.

    Abstract: Device to detect at least an analyte, comprising a transparent substrate (2), having a first surface (3) with which a light source (7) is associated, and a second surface (4) on which a plurality of biological protein probes (12) are disposed, a layer (6) of polymer being interposed between said second surface (4) and said biological protein probes (12). A marker (fluorophore) is associated with said analyte, having determinate characteristics of fluorescence and/or phosphorescence correlated to the emission wavelength of the light source (7). Said light source (7) is suitable to emit a light radiation in a range of wavelengths equal to 400-550 nm, inside which range the absorption peak of said marker (fluorophore) used is comprised. The value of the distance (“s”) between the wavelength corresponding to the absorption peak of the marker (fluorophore) and the wavelength corresponding to the emission peak of fluorescence (phosphorescence) is comprised between 25 and 150 nm.

    Abstract: Plasmonic condensers for generating surface plasmon at an evanescent wave surface can include a substrate layer, a metal layer comprising the evanescent wave surface; and a media layer disposed between the metal layer and the substrate layer. The media layer can be active or passive and can include a source of radiation that interacts with the metal layer to create surface plasmons that are not substantially optically detectable as far field radiation until an interfering object is brought into proximity with the evanescent wave surface. When an interfering object such as a sample or specimen is brought into proximity with the evanescent wave surface, it causes coupling of at least some of the surface plasmons into propagating radiation detectable by an objective lens. Systems, methods, and the like are disclosed, as are features of a plasmonic meta-materials illuminator.
