摘要: This disclosure relates to methods and devices to count particles of interest, such as cells. The methods include obtaining a fluid sample that may contain particles of interest; counting all types of particles in a portion of the sample using a first electrical differential counter to generate a first total; removing any particles of interest from the portion of the fluid sample; counting any particles remaining in the portion of the fluid sample using a second electrical differential counter after the particles of interest are removed to generate a second total; and calculating a number of particles of interest originally in the fluid sample by subtracting the second total from the first total, wherein the difference is the number of particles of interest in the sample. These methods and related devices can be used, for example, to produce a robust, inexpensive diagnostic kit for CD4+ T cell counting in whole blood samples.

摘要: Various systems, methods, and devices are provided for focusing particles suspended within a moving fluid into one or more localized stream lines. The system can include a substrate and at least one channel provided on the substrate having an inlet and an outlet. The system can further include a fluid moving along the channel in a laminar flow having suspended particles and a pumping element driving the laminar flow of the fluid.

摘要: The present invention generally relates to methods and compositions to determine viability of an organ for transplantation and other medical purposes. One aspect of the invention relates to a method for assessing the viability of an organ by measuring the energy parameters to determine the energy level of the organ by determining the stored cellular energy (e.g., ATP levels), and/or energy consumption over a particular time period of viability. The energy parameters can be compared to reference energy parameters as a highly accurate and reliable prediction of viable cell yield, and organ viability. Another aspect of the invention relates methods to preserve or extend the time period of viability of an organ any combination of (i) preservation perfusion of the organ to prevent ischemic damage, (ii) chemical metabolic suppression of the organ e.g., using metabolic suppressants, (iii) metabolic suppression by physical or environmental conditions, e.g., sub-zero non-freezing storage.

摘要: The invention features devices for mixing fluids, e.g., for lysing cells, and methods of use thereof. One device is based on the ability to control the flow of fluids, e.g., by contact angle and channel size. Fluids in this device can be divided to form segments of controlled volume, which are then brought together to initiate mixing. An exemplary use of the device is for the lysis of single cells. Another device is based on the ability to two mix two fluids in a channel and affinity capture of analytes. The devices can be integrated on the same chip with other devices, for example, for cell handling or analysis of DNA, mRNA, and proteins released from the lysis of a cell.

摘要: Microfluidic devices and methods for the encapsulation of particles within liquid droplets are disclosed. The new methods and devices form 1-100 picoliter-size monodisperse droplets containing the particles, such as single cells, encapsulated in individual liquid droplets. The particles can be encapsulated in droplets of a fluid by passing a fluid containing the particles through a high aspect-ratio microchannel to order the particles in the fluid, followed by forming the fluid into droplets. The resulting fraction of the liquid droplets with a single particle (e.g., a cell) is higher than the corresponding fraction of single-particle liquid droplets predicted by Poisson statistics.
