A METHOD AND DEVICE FOR MOVING AND DISTRIBUTING AQUEOUS LIQUIDS AT HIGH RATES ON POROUS, NONWOVEN SUBSTRATES
A material for manipulating liquid volumes includes a porous substrate having first and second surfaces; and a liquid-manipulating pattern disposed on the first surface, the pattern having a first reservoir connected to a target point via a first wedge-shaped transport element to enable liquid transport from the target point to the first reservoir regardless of gravity, wherein the first surface is one of hydrophobic or superhydrophobic, and wherein the first wedge-shaped transport element is one of superhydrophilic when the first surface is hydrophobic, superhydrophilic when the first surface is superhydrophobic, and hydrophilic when the first surface is superhydrophobic. The pattern can include a second reservoir connected to the target point via a second wedge-shaped transport element to enable liquid transport from the target point to the second reservoir regardless of gravity.
SYSTEMS AND METHODS FOR WHOLE CELL ANALYSIS
The present disclosure relates to systems and methods for whole cell analysis. In particular, the present disclosure relates to single cell genomic analysis (e.g., gene expression analysis.
IMMOBILIZING FLUIDIC SAMPLE FOR INHIBITING SPATIAL BROADENING
A method of handling a fluidic sample in a sample separation device includes at least partly immobilizing the fluidic sample by an immobilizing agent inhibiting spatial broadening of the fluidic sample, and subsequently at least partly releasing the fluidic sample from the immobilizing agent.
IMMUNOASSAY METHODS AND DEVICES
A device for performing immunoassay tests includes a readable device for performing immunoassay tests having a platform with at least two sample receiving units. Each sample receiving unit is fluidly connectable to at least two test units, each of which includes a reagent incubation chamber fluidly connected to a separation unit connected to a detection chamber. The platform includes a volume indication unit for detecting the presence of a predetermined volume of the liquid biological sample, and a reading device for performing immunoassay tests. A recognition unit recognizes the presence of the readable device and/or extracts information from a legible identification unit of the readable device. A first optical sensor detects the presence of a binding pair of molecules in the separation unit and/or the presence of free molecules in the detection chamber. A second optical sensor detects the presence of a liquid biological sample in the overflow chamber.
FILTER FILM AND USE THEREOF
A filter film includes a through-hole and a recessed portion having a size capable of capturing one particle, in which the recessed portion is open to one face of the filter film, the through-hole in the one face has a shape or a size such that the one particle is not capable of passing through the through-hole, and the through-hole and the recessed portion are disposed close to each other.
Acoustic Cell Separation Techniques and Processes
Beads with functionalized material applied to them are exposed to an acoustic field to trap, retain or pass the beads. The beads may include or be free of ferro magnetic material. The beads may be biocompatible or biodegradable for a host. The size of the beads may vary over a range, and/or be heterogenous or homogenous. The composition of the beads may include high, neutral or low acoustic contrast material. The chemistry of the functionalized material may be compatible with existing processes. The acoustic field may be generated, for example, in an acoustic angled wave device or in an acoustic fluidized bed.
Microfluidic device and array disk
The invention relates to microfluidic devices and array disks for one-pot isolated chemical reactions. The array disks comprise a plurality of sectors in which each sector comprises one microfluidic device. The microfluidic devices comprise a fluid delivery channel and an array of wells wherein the fluid delivery channel delivery fluid into the wells in a serpentine arrangement. In some embodiments, the fluid delivery channel is directly above the array of wells. In other embodiments, the fluid delivery channel is offset from the array of wells so that side channels branching from the fluid delivery channel delivers fluid into the wells. The well of the microfluidic device comprises a gas-permeable membrane that forms the floor, well, or at least a portion of the floor or wall of the well. In preferred embodiments, the well is cylindrical.
Fluidic devices with nanoscale manifolds for molecular transport, related systems and methods of analysis
Fluidic devices with a primary transport nanochannel(s) intersected by at least one nanoscale manifold for active control of capture, manipulation and transport of analyte molecules. The at least one manifold can be an array or network of nanochannels, nanoslits or nanoelectrodes joined to a common voltage or pressure source. A respective nanoscale manifold can be configured to allow for precise and active control of driving forces applied to the primary transport nanochannel(s) to drive molecular transport through the various regions along the transport nanochannel(s). The at least one manifold can generate monotonic force gradients with a limited or reduced number of independent input potentials and/or pressures applied to the device.
Photonic superlattice-based devices and compositions for use in luminescent imaging, and methods of using the same
