The optical waveguide is configured and positioned such that the micro-fluidic channel (106) is illuminated with an evanescent tail of excitation light guided by the optical waveguide. The rejection filter is positioned such that fluorescence from activated fluorescent tags present on top of the fourth layer (104) is filtered before falling onto the detector element (107). The rejection filter is configured to reject the wavelength range of the excitation light and configured to transmit the wavelength range of fluorescence from the activated fluorescent tags towards the detector element (107).

    Abstract: The present disclosure concerns an apparatus (10) and method for reading out an optical chip (20). A light source (13) is arranged for emitting single mode source light (S1) from its emitter surface (A1) towards an optical input (21) of the optical chip (20). A light detector (14) is arranged for receiving measurement light (S2) impinging onto its receiver surface (A2) from an optical output (22) of the optical chip (20), and measuring said received measurement light (S2). The emitted source light (S1) is aligned to enter the optical input (21) of the optical chip (20) and the measurement light (S2) is aligned back onto the receiver surface (A2). The receiver surface (A2) is larger than the emitter surface (A1) for facilitating the overall alignment.

    Abstract: Methods for covalently modifying surfaces of various substrates are disclosed, along with various substrates having surfaces modified by such methods. Candidate surfaces include various polymeric, siliceous, metallic, allotropic forms of carbon, and semiconductor surfaces. The surfaces are exposed to a reagent, having molecules each comprising a nitrenogenic group and a functionalizing group, in the presence of energized charged particles such as electrons and ions, photons, or heat, which transform the nitrenogenic reagent to a nitrene intermediate. The nitrene covalently reacts with any of various chemical groups present on the substrate surface, thereby effecting nitrene addition of the functionalizing groups to the substrate surface. The functionalizing groups can then participate in downstream chemistry whereby any of a large variety of functional groups, including biological molecules, can be covalently bonded to the surface, thereby dramatically altering the chemical behavior of the surface. Such functionalizations of the surface can be done in a single reactive step or in multiple reactive steps.

    Abstract: Disclosed is a microfluidic detection device including a circuit substrate and a transparent substrate. The circuit substrate is provided with at least one first light-emitting device used to emit a detection beam, a photodetector used to receive the detection beam and send out a sensing signal, and a control circuit electrically connected to the first light-emitting device and the photodetector. The transparent substrate overlaps the circuit substrate and is provided with a microfluidic channel and a light guide structure. The light guide structure has a light incident surface disposed corresponding to the first light-emitting device and a light exiting surface disposed corresponding to the photodetector. The light guide structure extends from each of the light incident surface and the light exiting surface to the microfluidic channel and is adapted to transmit the detection beam into and out of the microfluidic channel.
