Abstract: A liquid directing sample container includes a well. The well has sides and a floor. The sides having a non-circular profile having an interior angle that, at a target location within the well, is smaller than other interior angles of the profile to wick liquid towards the target location. The floor is sloped downward towards the target location.

Abstract: An example system includes an input channel having a first end and a second end to receive particles through the first end, a separation chamber, at least two output channels, and an integrated pump to facilitate flow through the separation chamber. The separation chamber is in fluid communication with the second end of the input channel. The separation chamber has a passive separation structure, the passive separation structure including an array of columns spaced apart to facilitate separation of particles in a flow based on a size of the particles. Each output channel is in fluid communication with the separation chamber to receive separated particles. The integrated pump is positioned within at least one of the input channel or one of the at least two output channels.

Abstract: In an example implementation, a reagent storage system for a microfluidic device includes a microfluidic chamber formed in a microfluidic device. A blister pack to store a reagent includes an electrically conductive membrane barrier adjacent to the chamber. A thinned region is formed in the membrane barrier, and a conductive trace is to supply electric current to heat and melt the thinned region. Melting the thinned region is to cause the membrane barrier to open and release the reagent into the chamber.

Abstract: An apparatus includes a sample carrier having wells. Each of the wells has sides and a floor forming an interior. A surface enhanced Raman spectroscopy (SERS) structure is within the interior of each of the wells. A pneumatic port is connected to the interior of each of the wells. A pneumatic passage is connected to the pneumatic ports.

Abstract: An example device includes a substrate having a first surface, an electrowetting force generation layer above the first surface, and a nanostructure layer formed above the electrowetting force generation layer, the nanostructure layer having nano-fingers formed thereon. The electrowetting force generation layer is to generate an electrical field to selectively move at least one reactant on the nano-fingers of the nanostructure layer.

Abstract: In an example, an apparatus is described that includes a light source, a holographic optical element, a sampling apparatus, and a detector. The light source is configured to emit a beam of excitation light. The holographic optical element is arranged to convert the beam of excitation light into a plurality of beams of excitation light. The sampling apparatus is arranged to project the plurality of beams of excitation light onto a surface outside the apparatus as a two-dimensional pattern of projection points. The sampling apparatus is further arranged to collect scattered radiation emitted by the surface in response to the two-dimensional pattern of projection points. The detector detects a frequency shift in the scattered radiation.
