Examples of the disclosure relate to an apparatus for analysing fluid samples. The apparatus is sized and shaped so that it can fit into an input port of an electronic device. The input port could be an existing port of the electronic device such as an input port for a memory card or a charger. The electronic device can be configured with a heat transfer means so that, when the apparatus is inserted into the electronic device, heat from the electronic device can be used to control the temperature of a fluid sample within the apparatus. This can enable the reaction conditions within the apparatus to be controlled.

Engineered nanoscale multicomponent particles are introduced and are called “quants.” Methods and apparatuses for producing such multicomponent nanoparticles are provided. A single quant can be manufactured to contain a variety of different internal component molecules. Likewise, a plurality of such quants may be manufactured wherein the plurality of quants are suspended in an aqueous solution. Typically, quants are produced in quantity and concentration adequate to support human scale therapeutics. In some embodiments, millions or billions of quants are suspended in a volume of aqueous solution for delivery to a patient. When manufactured to the same specification, the plurality of quants are uniform in size, uniform in chemical composition, and therefore uniform in functionality. Functional uniformity is an essential aspect of quants, manifested in design and production. By controlling the variables of manufacture, such as particle size and composition, and by redefining a drug dose as the measured number of quants delivered (as opposed to measuring a drug dose by the mass of its active ingredient), the performance of these nanoparticle-based drugs introduce significant efficiencies and much higher value products to the expanding therapeutics market.

The present disclosure provides systems and methods for sample analysis. The system comprises a container. The container comprises a sample receptacle and a cap, and the cap comprises a reservoir for retaining a composition, a first piercing member and a first pierceable barrier for sealing said composition within said reservoir. There is also provided a method for sample analysis.

A system for testing for an analyte includes a test strip. The test strip includes a first flow path. The test strip further includes a heating element in communication with a heating area of the first flow path, for heating a sample in the first flow path. The test strip further includes an e-gate, the e-gate in the first flow path, the e-gate separating the heating area from a detection area of the first flow path.

A dielectrophoretic detection device including a chip, with a flow channel having at least one inlet and one outlet, and at least a detection area configured to detect analytes trapped on functionalised beads flowing within the flow channel, first and second electrode assemblies shaped as rows of parallel pillars extending a the height of the flow channel, and configured to generate under electric tension an electric field to form an electrical barrier, and preventing the beads to cross the barrier and drawing the beads to the detection area by dielectrophoretic forces where they are clustered and concentrated. The device may be provided with multiple rows of parallel pillars of electrode assemblies extending over the height of the flow channel, forming multiple concentration lines. The flow channel may be provided with further rows of parallel pillars of electrode assemblies crossing the flow channel in a transverse direction, forming further incubation lines.

A system configured to determine the load in a liquid sample of predetermined antigens is provided. The system comprises a measurement chamber configured for receipt therein of the liquid sample, a sensor circuit, and an analysis unit. The sensor circuit comprises a plurality of working electrodes, each comprising antibodies on its surface associated with one of the predetermined antigens, at least one reference electrode, and at least one counter electrode. Proximal ends of the electrodes are disposed on a reading zone of the sensor circuit, the reading zone being disposed within the measurement chamber. The analysis unit is configured to facilitate the determination of the load of each of the antigens by measuring electrical properties of the electrodes.

A sample testing device is disclosed. The sample testing device can include a first compartment that is configured to receive a test sample, a second compartment that is configured to receive the test sample, a separator that is disposed between and separating the first compartment and the second compartment, and a mechanical lock structure that is configured to lock and unlock a movement of the separator. When the mechanical lock is unlocked, the separator opens to transfer the test sample from the first compartment to the second compartment. The sample testing device can include a sensing assembly.

Methods for selectively adding one or more reagents are provided. In certain aspects, the methods include selectively merging one or more droplets of a plurality of droplets with one or more droplets of a plurality of reagent droplets based on detection of a property. Systems, devices and kits for practicing the subject methods are also provided. The subject disclosure may find use in a wide variety of applications, such as increasing the accuracy and/or efficiency of single-cell sequencing, detection of cancer or other diseases, monitoring disease progression, analyzing the DNA or RNA content of cells, and other applications in which it is desired to detect and/or quantify specific target cells.

Provided is a high-stability ion-selective membrane (ISM) containing a thallium porphyrin complex as an ionophore, the ISM containing: a compound represented by the following formula (1); a polymer; and a membrane solvent.
