Device and determination system using same
The present disclosure relates to a device including a reagent portion in which a chemiluminescent indicator and a chemiluminescent substrate for the indicator are disposed, and a base on which the reagent portion is formed. The chemiluminescent indicator and the chemiluminescent substrate are disposed independently from each other in the reagent portion in such a manner that the chemiluminescent indicator and the chemiluminescent substrate can react with each other when a sample is supplied to the reagent portion. The present disclosure also relates to a remote diagnosis system including an imaging terminal for detecting a luminescent signal generated when a reagent is supplied to the device and an information processing unit for processing luminescent signal data obtained by the imaging terminal. The imaging terminal and the information processing unit can bi-directionally communicate with each other via a network.
MICROFLUIDIC DEVICE
Microfluidic devices that are configured to use centrifugal forces to bias particles into one or more capture regions based on their individual sizes are described.
PIPETTE TIP ADAPTER
An adapter for connecting an array of pipette tips having through bores with conical upper ends to a multichannel air displacement pipettor having a plurality of ports with compliant internal sealing surfaces. The adapter comprises a planar base with an array of openings extending between its top and bottom surfaces. Sealing tubes project upwardly from the top surface, and tip mounting tubes project downwardly from the bottom surface, with pairs of sealing tubes and tip mounting tubes being arranged coaxially and in communication with respective ones of the openings in the base. The tip mounting tubes are externally dimensioned and configured for insertion into the conical upper ends of the pipette tips, and the sealing tubes are externally configured and dimensioned for insertion into the ports of the pipettor and into sealing interengagement with their compliant internal sealing surfaces.

A fluidic device including a substrate having a well array that includes regularly arranged wells that have a same shape and are open to a surface of the substrate, and a cover member facing the well array. The well array and the cover member are positioned to have a space therebetween, which forms a flow path through which a fluid flows, and the wells including a well A and a well B closest to the well A satisfy formula (1): 0.8≤Da/Dab<1 . . . (1) where Dab is a distance between a centroid Ca of an opening of the well A and a centroid Cb of an opening of the well B, and Da is a diameter of a circle having a same area as the opening of the well A.
Materials transport device for diagnostic and tissue engineering applications
Devices that can transport biological materials are described. The devices incorporate capillary channeled fibers that can effectively transport living cells as well as other biological materials such as nutrients, growth factors, waste materials, etc. The devices can include a sorptive material at one end of the fibers that can improve transport of materials through the devices. The devices can differentially transport different cell types, particularly when the fibers are held in a vertical orientation. Diagnostic devices that incorporate the capillary channeled fibers are described that can be utilized to separate cell types from one another. Tissue engineering scaffolds that incorporate the capillary channeled fibers are described that can more efficiently transport materials into and out of the scaffolds.
Method of transferring material from microfabricated device
Methods of transferring material from a first device having an array of microwells to a second device is provided. In some examples, the first device and the second device are moved together toward a stopper plate and impinge on the stopper plate. In other examples, the first device and the second device are kept stationary and an impinging device is impacted on a mounting structure enclosing the first and second devices, causing material transfer from the microwells of the first device to the second device. Apparatus for carrying out the transfer of material is also disclosed.
