Abstract: The present disclosure is drawn to a method of labeling and identifying microfluidic samples. The method can include tagging a first microfluidic sample with a first combination of markers to obtain a first labeled sample; tagging a second microfluidic sample with a second combination of markers that is different than the first combination of markers to obtain a second labeled sample; introducing a common variable to the first labeled sample and the second labeled sample. The common variable can generates a first interaction with the first labeled sample that is different than a second interaction or lack of interaction with the second labeled sample. The method can further include based on the first interaction, identifying the first labeled sample by assaying for the first combination of markers.

Abstract: A device may include a substrate, a first fluid processing chip, a second fluid processing chip, a tapered channel, and a fluid actuator. The first fluid processing chip may be disposed on the substrate and may process a micro-volume of fluid. The second fluid processing chip may be disposed on the substrate and co-planar with the first fluid processing chip. The second fluid processing chip may process at least a portion of the micro-volume of fluid. The tapered channel may be disposed between the first and second fluid processing chips to transport the at least the portion of the micro-volume of fluid from the first fluid processing chip to the second fluid processing chip. The fluid actuator may be disposed proximate to the tapered channel and may control movement of the at least the portion of the micro-volume of fluid within the tapered channel.

Abstract: In one example in accordance with the present disclosure, a cell analysis system is described. The cell analysis system includes at least one cell analysis device. Each cell analysis device includes a channel to serially feed individual cells from a volume of cells into a lysing chamber. The cell analysis device also includes at least one feedback-controlled lysing element in the lysing chamber to agitate a cell. The cell analysis system also includes a controller to analyze the cell. The controller includes a lysate analyzer to analyze properties of the lysate and a rupture analyzer to analyze parameters of an agitation when a cell membrane ruptures.

Abstract: An example system includes an input channel to receive particles through a first end, a separation chamber, at least two output channels, an integrated pump to facilitate flow through the separation chamber and a cell analysis portion. The separation chamber is in fluid communication with a second end of the input channel. The separation chamber has a passive separation structure including an array of columns spaced apart to facilitate separation of particles into at least two flow paths based on a size of the particles. The size associated with a first flow path of the at least two flow paths corresponds to a cell. A first output channel is to receive the first flow path corresponding to a cell. The cell analysis portion is coupled to the first output channel and is to perform at least one analysis associated with cells in the first output channel.

Abstract: Examples relate to conducting Polymerase Chain Reactions (PCR). An example device for conducting PCR includes a primer applicator to add a first multi-primer set of a primer library to a first test chamber of a test chamber array. The example device also includes an amplification analyzer to determine if amplification has occurred in the first test chamber. The example device includes a device controller to instruct the primer applicator to apply a second multi-primer set of the primer library to the first test chamber in response to a detection by the amplification analyzer that amplification has not occurred in the first test chamber. Example devices instruct the primer applicator to apply a first primer subset of the first multi-primer set to a second test chamber of the test chamber array in response to a detection by the amplification analyzer that amplification occurred in the first test chamber.

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 surface enhanced Raman scattering (SERS) sensor may include a substrate, an electrically conductive layer having a first portion spaced from a second portion by a gap, an electrically resistive layer in contact with and extending between the first portion and the second portion of the electrically conductive layer to form an electrically resistive bridge across the gap that heats the nano fingers in response to electrical current flowing across the bridge from the first portion to the second portion and nano fingers extending upward from the bridge.
