The present invention relates to an automated analytical system and an automated method for separating and detecting an analyte, as well as an automated analytical instrument.

A data receiver thread is continuously executed to receive in which signals indicating a fluid parameter. A predetermined time quantity of the signals is repeatedly buffered. Upon completion of the buffering of each predetermined time quantity of the signals, a data processing thread is initiated that executes on the just completed buffered predetermined time quantity of signals. Upon completion of each data processing thread, data from the just completed data processing thread is passed to a data plotting thread. Results of the data plotting thread are displayed on a portable electronic device while the data receiver thread is being executed.

The present invention provides a novel target analysis chip and analysis method for directly detecting a target such as a microRNA without performing PCR.

A device for extracting a nucleic acid from a sample liquid includes a heating element configured to be connected to an extraction nucleic acid. The extraction nucleic acid is at least partly complementary to the nucleic acid to be extracted from the sample liquid. The heating element is heatable to a temperature that is equal to or higher than a denaturing temperature of the nucleic acid bound to the extraction nucleic acid.

A microporous substrate for detection of surface bound target analyte molecules includes a microporous substrate material having opposed surfaces and tapered micropores extending through the substrate with the micropores having wider openings on one side of the substrate compared to the other side. The micropores have bound therein analyte specific receptors complementary to the target molecules. When a liquid sample containing the target analyte molecules with optical probes attached to the target molecules is flowed through the substrate, they bind to their complementary analyte specific receptors and emit light. This microporous substrate structure gives an increase in the collection efficiency of light emitted from optical probes when the light is detected by a light detector spaced from the side of the microporous substrate facing the larger micropores openings compared to a light collection efficiency of light emitted from the optical probes when the micropores are straight and not tapered.

The present disclosure provides a real-time thermocycler, comprising: a well for storing a sample comprising a target and fluorescence molecules, a thermal unit for adjusting a temperature of the sample, an excitation unit for exciting the fluorescence molecules of the sample via radiation, a detection unit for detecting a fluorescence signal from the sample, and a controller for controlling the excitation unit to adjust an intensity of the excitation of the sample based on information about the target, such that the fluorescence signal is in a working range of the detection unit.

A microfluidic chip is disclosed herein. In a specific embodiment, the microfluidic chip comprises at least one microfluidic reservoir having a wall portion and a heat transfer sealing layer cooperating with the wall portion for receiving a sample to be tested. The heat transfer sealing layer is arranged to be contiguous with the sample to be tested. The microfluidic chip further comprises an active temperature control device arranged to provide structural support to the heat transfer sealing layer and operable to control a temperature of the sample via transmission of heat through the heat transfer sealing layer. A detection module is also disclosed.

The present disclosure relates to a structure capable of simultaneously purifying and detecting a nucleic acid by directly applying a sample, and more particularly, to a structure capable of performing sample preparation, loop-mediated isothermal amplification, detection and analysis steps on a single chip by applying lab-on-paper technology, and capable of finally determining whether the disease or bacterial is infected by moving the sample in a lateral flow method.
