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: 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: Techniques for separating particles of interest from whole blood are disclosed. An example particle separation chip includes a first inlet on the particle separation chip for receiving whole blood and a second inlet on the particle separation chip for receiving a lysis buffer. The particle separation chip also includes a mixer to mix the whole blood with the lysis buffer to provide lysis of red blood cells in the whole blood. The particle separation chip also includes a buffer exchanger to exchange the lysis buffer for a dielectrophoresis buffer to produce a solution that enables dielectrophoretic separation of particles of interest. The particle separation chip also includes a separator coupled to an output of the buffer exchanger to separate the particles of interest from other particles in the solution via dielectrophoretic separation and deliver the particles of interest to an outlet on the particle separation chip.

Abstract: Fluid classification may include: receiving sensed data for the fluid; modeling the sensed data in a frequency domain; synthesizing a model of the sensed data from the frequency domain to a time domain response and converting the time domain response to a time frequency graphical representation in the form of a color map. Predetermined characteristics of the time frequency graphical representation are identified through computer vision and compared to at least one corresponding signature characteristic of a predetermined fluid type to identify the fluid as a fluid type.

Abstract: An analysis assembly is provided. The analysis assembly includes an analysis chip disposed on a supporting platform aligned in an x-y plane, wherein an active surface of the analysis chip is aligned along a z-axis opposite the supporting platform. A mounting assembly joined to the supporting platform is configured to hold the analysis chip in an analysis vessel, and wherein the z-axis is in alignment with a longitudinal axis of the analysis vessel.
