A tunable inertial sheathing (TIS) system and methods for particle-size-insensitive high-throughput single-stream focusing of particles suspended in a particle-carrying fluid are provided. The TIS conditions particles to distribute locally within one of compartments of inertial force field, followed by an inertial focusing to migrate it to a single foci. For the particle localization, the TIS system introduces an arbitrary form of peripheral sheathing by generating and accumulating sheath fluid from particle-carrying fluid through a combination of inertial focusing, channel bifurcation and channel confluence. Multiple forms of the TIS system are also provided, each including one main channel and at least one bypass channel. The main channel includes and cascades at least three segments, at least one bifurcating junction and at least one confluence junction.

The present invention relates to a device (10) for use in fluid sample analysis. It is described to position (310) a top part (20) of the device (10) adjacent to a base part (30) of the device so as to define a fluidic receiving region in between, the top part being provided with a through opening fluidly connected to the fluidic receiving region, and the bottom part being provided with a radiation window adjacent to the fluidic receiving region. A fluidic sample is supplied (320) through the opening (24). The fluidic sample is moved laterally (330) in the fluid receiving region without the use of an intermediary membrane between the top part and the base part. A radiation is emitted (340) to the fluid receiving region. A radiation is detected (350) that is reflected by the device. A presence of the fluidic sample is determined (360) on the basis of a measured reflectance value based on the detected radiation.
