In an example implementation, a substance detection device includes a substrate having nanoimprinted chamber walls and nanostructures. The chamber walls define a chamber and the nanostructures are positioned within the chamber to react to a substance introduced into the chamber. A two-dimensional (2D) orifice plate is affixed to the chamber walls and forms a top side of the chamber.
Abstract:
A system includes an illumination source, a detector and a processor. The detector acquires spectral measurements of a sample under test under at least one varying condition. The processor processes the measurements to generate at least one spectral representation that includes Raman spectra and at least one spectral representation that includes non-Raman spectra.
Abstract:
A spectroscopic device is provided. The spectroscopic device includes a plurality of design groups on a substrate. Each design group includes a plurality of collapsed groups separated by bare regions of substrate, wherein the edges of each design group is configured to enhance the pinning of a solvent drying line at the edge of the design group. Each collapsed group comprises at least 2 flexible columnar structures, and each flexible columnar structure comprises a metal cap.
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.
Abstract:
A luminescence-enhancement system can include a luminescence-enhancement sensor having a substrate and a group of nanofingers with individual nanofingers that can be flexible and include a support end attached to the substrate, a distal tip positioned distally with respect to the substrate, and a middle portion between the support end and the distal tip. A coating of a metal or metal alloy can be applied to the substrate and the distal tip that is conductively continuous. The middle portion can be devoid of the coating or the coating at the middle portion is conductively discontinuous. A liquid ejector can be present and can include a jetting nozzle to eject a liquid droplet having a volume of 2 pL to 10 μL. The group of nanofingers and the jetting nozzle can be positionable relative to one another for the droplet to be deposited on the group of nanofingers.
