摘要: The invention relates to a method and an apparatus for the investigation of a sample material by multiple sample light spots (501) generated by evanescent waves. An array of source light spots (510) is generated by a multi-spot generator, e.g. a multi-mode interferometer (106), and mapped onto sample light spots (501) in a sample layer (302) by (micro-)lenses (202, 203) or by the Talbot effect. The input light (504) of the source light spots (510) is shaped such that all of it is totally internally reflected at the interface between a transparent carrier plate (301) and the sample layer (302). Thus the sample light spots (501) consist of evanescent waves only and are restricted to a limited volume. In a preferred application, fluorescence stimulated in the sample light spots (501) is detected with spatial resolution by a CCD array (401).

摘要: The invention relates to a microfluidic device for detection of a substance in a sample fluid, and to a cartridge for performing a biological assay, containing such a device. The microfluidic device comprises two housing parts (52, 54) with a porous membrane (50) there between. Each housing part has recesses, or channel parts, (56-1, 56-2, 56-n, 58-1, 58-2, 58-n) that are connected via a recess of the opposite housing part, and through the membrane (50), such that an unbranched channel is defined for the sample fluid. At one or more of the positions where the channel crosses the membrane (50), a spot (48-1, 48-2, 48-n) with an immobilized indicator substance is present, to which a target substance in the sample fluid may bind. An advantage of the present device is that in principle all of the sample fluid passes each spot. Hence there is no need to recirculate and/or mix the sample fluid, as is the case in devices with parallel flow-through paths for the fluid. The device will therefore be simpler, and give a more reliable detection result.

摘要: The invention relates to a process for the fabrication of a polymeric optical microstructure, being supported or not by a substrate, starting from a thermoplastic polymer, wherein a thermoplastic polymer is blended with an UV curable resin and a thermally stable photo-initiator, to obtain a blend having a lower viscosity than the viscosity of said polymer, said blend being molded and the molded blend being cured by means of UV radiation to obtain a polymeric optical micro structure. Such a process prevents the common problems, which arise with molding of conventional thermoplastic polymers and conventional UV curing when only one of the components of the blend is used.
