Abstract: In one example, an analysis chip includes a substrate for surface-enhanced spectroscopy including an ordered nanostructure surface to receive a liquid including a number of analytes. The received liquid is to be guided by the ordered nanostructure surface over the substrate to separate the number of analytes.

Abstract: A system and a method for sorting particles are provided. An example of a particle sorting system includes an array that includes a number of microfluidic ejectors. An optical sensor is focused on the array. A controller is used to identify a target particle proximate to a microfluidic ejector, and activate the microfluidic ejector to eject the target particle into a collection vessel.

Abstract: A system and a method for the batch sorting of particles are provided. An example of a batch sorting system includes a microfluidic ejector, a flow channel fluidically coupled to the microfluidic ejector at one end, and a reservoir coupled to an opposite end of the flow channel from the microfluidic ejector. A counter is disposed in the flow channel upstream of the microfluidic ejector to count particles prior to ejection from the microfluidic ejector. An optical sensor is to image the flow channel. A controller is configured to locate a target particle in the flow channel based, at least in part, on the image and capture the target particle in a collection vessel based, at least in part, on a count from the counter.
