Methods and devices for testing a biological sample are provided. A tape includes multiple channels or reservoirs having inlet and outlet ports. One tape having biological sample disposed in its channels is temporarily mated with another tape having reagents disposed in its channels via a serpentine belt and compression roller assembly. Pulsed fluidic operations combine the reagents and the biological sample for subsequent observation, detection, storage and/or disposal. Fluidic transfer is provided in a uniform operation or in conjunction with a sensory feedback assembly.

The invention is to provide a method of profiling a sample comprising a plurality of cells, the method comprising: flowing cells from the sample through a first array of pillars to obtain one or more distribution profiles of cells sorted by the first array; flowing cells from the sample through a second array of pillars that is different from the first array of pillars to obtain on one or more distribution profiles of cells sorted by the second array; and deriving a biophysical signature of the sample based on at least the one or more distribution profiles of the cells sorted by the first array and/or the one or more distribution profiles of the cells sorted by the second array. The method further comprises determining a health status of a subject based on the biophysical signature of the sample. The invention is also to provide a sample profiling system. In various embodiments, the distribution profile of cells in the output regions is indicative of one or more biophysical properties of the cells, which may include the size and deformability of the cells. The pillars in the first array and the second array may have a shape selected from the group consisting of a substantially L shape and a substantially inverse L shape, mirror reflections thereof or combinations thereof.

The present disclosure generally relates, in certain aspects, to droplet-based microfluidic devices and methods. In certain aspects, target nucleic acids contained within droplets are amplified within droplets in a first step, where multiple primers may be present. However, multiple primers may cause multiple target nucleic acids to be amplified within the droplets, which can make it difficult to identify which nucleic acids were amplified. In a second step, the amplified nucleic acids may be determined. For example, the droplets may be broken and the amplified nucleic acids can be pooled together and sequenced. As an example, new droplets may be formed containing the amplified nucleic acids, and those nucleic acids within the droplets amplified by exposure to certain primers.
