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.

Abstract: A fluid exit passage is at a location along a microfluidic channel. A fluid displacement device is proximate the location along the microfluidic channel. A constituent locator distinguishes a target constituent in a fluid within the microfluidic channel from remaining non-target constituents and locate the target constituent proximate the fluid exit passage. A controller selectively actuates the fluid displacement device when the target constituent is proximate the fluid exit passage to discharge the target constituent from the microfluidic channel through the fluid exit passage.

Abstract: An example of an apparatus includes a plurality of wells, wherein each well is to receive a cell culture and a cell culture liquid. The apparatus also includes a collector to contact the cell culture liquid in a well selected from the plurality of wells. The collector is to draw a microfluidic sample of the cell culture liquid from the well. In addition, the apparatus includes a sensor substrate to receive the microfluidic sample, wherein the sensor substrate is to be used to measure a characteristic of the cell culture liquid. Also, the apparatus includes a microfluidic channel to transport the microfluidic sample from the collector to the sensor substrate.
