  • Patent number: 9476827
    Abstract: The invention substantially relates to an imaging system for the chemical, biological or biochemical analysis of a sample (10), comprising a device (40) for holding the sample (10), a device (20) for optical detection, a lighting device (30), liable to emit a monochromatic light beam, and a wide aperture objective (f1), It is substantially characterized in that the objective (f1) is configured for, downstream of the sample (10): focusing the excitation light beam reflected at a point (C) located in the focal plane (FF) of said objective (f1), and transforming the retransmitted or scattered light beam into a quasi-parallel beam, and in that the system further comprises a device (70) for selectively blocking the collected light beam by said objective (f1).

  • Publication number: 20120142045
    Abstract: A method of detecting substances or reactions of substances in a sample, comprising: (i) providing a layer (CS) based on hydrogenated or unhydrogenated amorphous silicon with attached probes, (ii) bringing the layer (CS) in contact with the sample that may contain the substances that bind specifically to or reacts specifically with the probes, under appropriate conditions for the substances to bind to or react with the probes; (iii) optionally removing non-specifically bound or non-specifically reactive substances; and (iv) detecting the presence or amount of the specifically bound or reactive substances in the sample by surface plasmon resonance (SPR) and/or fluorescence, is described.
