The invention concerns a method, an assembly and a system for determining a characteristic property of a molecular interaction. The method includes providing a liquid sample including a particle capable of being in a state of equilibrium and in a state of non-equilibrium. The particle includes a marker in at least one of its state of equilibrium and state of non-equilibrium. The method further includes bringing the particle in a state of non-equilibrium by subjecting the sample to a condition jump comprising a jump in temperature and/or pressure; reading out the marker as a function of time during at least a portion of a relaxation time for said particle, and determining said characteristic property of said molecular interaction.

Described herein are systems relating to a continuous-flow instrument that includes all necessary components for digital droplet quantification without the need to introduce key reagents or collect and transfer droplets between stages of instrument operation. Digital quantification can proceed without any additional fluid or consumable handling and without exposing fluids to risk of external contamination.

The present invention provides self-contained systems, apparatus and methods for determining a chemical state, the system includes a stationary cartridge for performing the assay therein, the cartridge adapted to house at least one reagent adapted to react with a sample; and at least one reporter functionality adapted to report a reaction of the at least one reagent with the sample to report a result of the assay, a mechanical controller including a first urging means adapted to apply a force externally onto the cartridge to release the at least one reagent; and at least one second urging means adapted to apply a removable force to induce fluidic movement in a first direction in the cartridge and upon removal of the force causing fluidic movement in an opposite direction to the first direction, an optical reader adapted to detect the reaction and a processor adapted to receive data from the optical reader and to process the data to determine said chemical state.

Automation compatible removable lids are provided. The removable lids include a top surface surrounded by a peripheral rim. The removable lids further include septal portions configured to receive an extractor, such as a pipette tip, inserted therethrough. The septal portions are further configured to grip the extractor to facilitate lid removal.

The invention relates to a cartridge for an analysis method which is rotation-based and utilizes one-sided heat input. The cartridge has a planar main body in which a microfluidic channel-and-chamber structure is formed, with channels interconnecting multiple process chambers, a number of positioning and/or fastening elements, formed in the main body, for positioning and/or fastening the main body on/to a support plate of an analyzer for carrying out the analysis method, and a cover body which is fastened to the main body and which is one-sidedly arranged on a top side of the main body that faces away from a heat input side and which covers at least a chamber.

The present invention relates to methods for the analysis of nucleic acids present in biological samples, and more specifically to normalize a high resolution melt curve to assist in the identification of one or more properties of the nucleic acids. The present invention provides methods and systems that incorporate a background identification algorithm according to invention principles using raw melt curve data to identify reactions that are unrelated actual DNA melt reactions. Furthermore, a web-based application for analyzing experimental data is provided. The raw experimental data obtained from a variety of instruments is processed and analyzed on a server and presented to a user through a user interface (UI).

Systems, methods, and kits are provided wherein a temperature-sensitive reagent that emits a luminescent signal is used to adjust the identification of the temperature of a sample or to control thermocycling. In various illustrative embodiments, the sample is a PCR mixture.

A microfluidic device includes a channel through which a reaction solution flows. The channel passes through a reaction section having a plurality of temperature zones set at predetermined different temperatures. The channel includes, at least in the reaction section, a region where a cross-sectional area decreases in a feeding direction of the reaction solution.

The present disclosure relates to a fluid analyzing device that includes a sensing device for analyzing a fluid sample. The sensing device includes a microchip configured for sensing the fluid sample, and a closed micro-fluidic component for propagating the fluid sample to the microchip. The fluid sample can be provided to the micro-fluidic component via an inlet of the fluid analyzing device. And a vacuum compartment, which is air-tight connected to the sensing device, can create in the micro-fluidic component a suction force suitable for propagating the fluid sample through the micro-fluidic component.

The present invention relates generally to the field of chemical and biological sensors and in particular to micro electro-mechanical systems (MEMS) sensors for measuring fluid viscosity and detection of minute amounts of chemicals and biological agents in fluids. It is an object of the present invention to provide a sensor that will work in disposable cartridges with remote sensing that can measure dynamic changes of the functionalized cantilevers in liquid and gas environment.
