Abstract:
Die Erfindung betrifft einen Reaktionsträger (100) für eine mikrofluidische Vorrichtung (200) zur Bestimmung einer Nukleotidsequenz, umfassend mindestens eine erste Ausnehmung (101) und eine zweite Ausnehmung (102), wobei in der ersten Ausnehmung (101) erste Fängerprimer (121) und in der zweiten Ausnehmung (102) zweite Fängerprimer (122) an einer Festphase (110) immobilisiert sind, wobei die ersten Fängerprimer (121) von den zweiten Fängerprimern (122) verschieden sind. Ferner betrifft die Erfindung eine solche mikrofluidische Vorrichtung (200) und ein zugehöriges Verfahren (500) zum Bestimmen einer Nukleotidsequenz.
Abstract:
According to the invention, generally, a microfluidic aliquoting (MA) chip, adapted to fit in a Petri dish, has a center well (inlet) connected by a plurality of microchannels to a plurality of side wells (outlets). A relatively large (such as 120 μL) cell suspension having several cells may be injected into the inlet of the MA chip, and single cells may be substantially simultaneously and uniformly distributed, via positive pressure-driving flow, to the several (such as 120) side wells having single cells in less than 1 minute. The MA Chip has a high efficiency in cell recovery. Due to rapid isolation and easy identification of single cells, high cell viability, high enrichment factor, and convenient transfer of submicroliter single-cell suspension, MA Chips are well compatible with CTC isolation from blood, single-cell cloning, PCR, and sequencing.

Abstract:
Embodiments of the present application relate to patterned polymer sheets and processes to prepare the same for sequencing applications. In particular, flexible micro- and nano-patterned polymer sheets are prepared and used as a template surface in sequencing reaction and new polish-free methods of forming isolated hydrogel plugs in nanowells are described.
Abstract:
A system for automated microorganism identification and antibiotic susceptibility testing comprising a reagent cartridge, a reagent stage, a cassette, a cassette, stage, a pipettor assembly, an optical detection system, and a controller is disclosed. The system is designed to dynamically adjust motor idle torque to control heat load and employs a fast focus process for determining the true focus position of an individual microorganism. The system also may quantify the relative abundance of viable microorganisms in a sample using dynamic dilution, and facilitate growth of microorganisms in customized media for rapid, accurate antimicrobial susceptibility testing.

Abstract:
Apparatus and methods for analyzing single molecule and performing nucleic acid sequencing. An integrated device includes multiple pixels with sample wells configured to receive a sample, which, when excited, emits radiation; at least one element for directing the emission radiation in a particular direction; and a light path along which the emission radiation travels from the sample well toward a sensor. The apparatus also includes an instrument that interfaces with the integrated device. Each sensor may detect emission radiation from a sample in a respective sample well. The instrument includes an excitation light source for exciting the sample in each sample well.
Abstract:
A sample loader for loading a liquid sample into a plurality of reaction sites within a substrate is provided. The sample loader includes a first blade, and a second blade coupled to the first blade. The sample loader further comprises a flow path between the first blade and second blade configured to dispense a liquid sample to a substrate including a plurality of reaction sites. Further, in various embodiments the liquid sample has an advancing contact angle of 85 +/- 15 degrees with the first and second blade. Furthermore, loading of the liquid sample dispensed from the flow path to the plurality of reaction sites may be based on capillary action.
