A microfluidic diagnostic chip may comprise a main fluid channel comprising a main pump, a secondary fluid channel branching off from the main fluid channel, and a secondary pump within the secondary fluid channel wherein the secondary pump is to pull a particle of analyte of a first size from a fluid passing through the main channel, the fluid comprising particles of analyte of the first size and of a number of larger sizes. A method of analyzing an analyte on a microfluidic chip may comprise pumping, with a main microfluidic pump, a fluid comprising an analyte particle through a main microfluidic channel fluidly coupled to a fluid slot and sorting the analyte particle within the fluid through a secondary microfluidic channel by pulling the analyte particle into the secondary microfluidic channel with a secondary microfluidic pump.

Fluid may be pumped within a microfluidic channel across a cell/particle sensor using a microscopic resistor. The microscopic resistor may be selectively actuated so as to heat the fluid within the microfluidic channel to a temperature below a nucleation energy of the fluid so as to regulate a temperature of the fluid for at least when the cell/particle sensor is sensing the fluid.

The present disclosure provides a microfluidic device comprising a set of micro-structured electrodes. The electrodes are made of a fusible alloy such as Field's Metal and are patterned on a layer of PDMS. The molten fusible alloy is poured over the patterned PDMA layer and a suction force is applied to ensure uniformity of flow of the molten metal.

A flow cell with a predetermined breaking barrier in a duct region of the flow cell. The flow cell has a cut-out in a substrate of the flow cell, which forms a portion of the duct region and has an opening in a surface of the substrate. The opening is hermetically sealed by a barrier film fused and/or glued to the surface and forming the predetermined breaking barrier. A layer is provided to be arranged over the barrier film. The layer can be stretched into the cut-out on breaking of the barrier film and formation of an access to a duct region section bounded by the barrier film and the layer.

Methods and apparatus for long read, label-free, optical nanopore long chain molecule sequencing. In general, the present disclosure describes a novel sequencing technology based on the integration of nanochannels to deliver single long-chain molecules with widely spaced (>wavelength), ˜1-nm aperture “tortuous” nanopores that slow translocation sufficiently to provide massively parallel, single base resolution using optical techniques. A novel, directed self-assembly nanofabrication scheme using simple colloidal nanoparticles is used to form the nanopore arrays atop nanochannels that unfold the long chain molecules. At the surface of the nanoparticle array, strongly localized electromagnetic fields in engineered plasmonic/polaritonic structures allow for single base resolution using optical techniques.
