Abstract: In an example implementation, a substance detection device includes a chamber with chamber walls, a chamber top, and a chamber bottom. A substrate comprises imprinted nanostructures positioned within the chamber, and the substrate is coupled to the chamber walls to form the chamber bottom. An inert gas is sealed within the chamber.

Abstract: In one implementation, a spectral microscope may comprise a substrate with a planar lens, the planar lens including a phase profile including an axial focus and an oblique focus, a light source to excite a signal of a particle among a plurality of particles, and a detector to receive light generated from the light source from the axial focus of the planar lens and a spectral color component of the excited signal of the particle from the oblique focus of the planar lens.

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.

Abstract: In an example implementation, a substance detection method includes sensing for fluid in a chamber of a substance detection device. When fluid is sensed in the chamber, the method includes sensing again for fluid in the chamber. When no fluid is sensed in the chamber, the method includes initiating a substance detection process.

Abstract: Provided in one example is an apparatus, including a substrate supporting a microfluidic channel, a bubble jet inertial pump supported by the substrate adjacent the microfluidic channel to pump fluid through the microfluidic channel and an optical sensor on a first side of the microfluidic channel. A light emitter on a second side of the microfluidic channel is to pass light across the microfluidic channel to the optical sensor.
