Abstract: An apparatus for detecting the presence of a specific molecular species in a mixture of species operates by first flowing the mixture through microfluidic channels onto a substrate to which the specific species bonds, then attaching electromagnetic radiation scattering particles to the bonded species, then scanning the substrate with a uniform flux of laser radiation and relating the intensity of the scattered portion of the radiation to the density of particles captured by the molecular species affixed to the substrate. The substrate can be scanned either by: 1. applying oscillating mirrors to reflect the laser beam and uniformly scan the substrate; 2. moving the entire laser relative to the substrate so that its beam uniformly scans the substrate; 3. moving the entire substrate uniformly in the x-y plane while keeping the laser and its beam fixed.
