The invention relates to a method for forming an emulsion (1) containing at least one dispersed phase (3) and one continuous phase (2) in a fluid microsystem (100). According to said method, flows (4, 5) are formed from different liquids flowing towards a dispersion region (10), and the emulsion (1) is formed from the liquids in the dispersion region (10). The flows (4, 5) run through a common channel (20) towards the dispersion region (10) and are located (4, 5) adjacently in relation to a first reference direction, and the emulsion (1) is produced during the flow of the liquids over a cross-sectional extension (11) which is provided in the dispersion region (10) and in which the cross-section of the channel (20) is extended in a second reference direction deviating from the first reference direction. The invention also relates to a fluid microsystem for forming an emulsion (1) containing a continuous phase (2) and at least one dispersed phase (3). The invention further relates to a fusion of drops in electrical fields.
摘要:
Total analysis systems and methods for simultaneously monitoring a suite of biological and/or chemical species in water and/or other process systems are disclosed. The system provides a sample- volume controlled sensor array comprising a fluid delivery device and a plurality of optical sensor elements for determining the presence and total concentrations of multiple analytes in the process system simultaneously. Delivery means are provided to deliver a metered quantity of sample fluid to the sensor array. Image identification algorithms are provided for identifying the analytes based on image intensity, color pattern, positional arrangement, and the like. The methods incorporate multivariate optimization algorithms to analyze multiple sensor responses. This produces analytical results that are typically difficult to obtain without full system or variable compensation. The improved array response may then be utilized to measure, monitor, and control the concentration of analytes in the chemical or biological sample or water system.

摘要:
The present invention generally pertains to a system for performing droplet inflation, and methods and kits comprising the same. The system comprises at least one microfluidic channel comprising one or more droplets flowing therein, one or more fluid reservoirs, one or more inflators, one or more inflator nozzles, and at least one mechanism for disrupting an interface between a droplet and a fluid. The present invention provides for the inflation of a relatively controlled volume of fluid into a droplet resulting in an increase in the volume of the droplet relative to its volume prior to inflation and, accordingly, dilution of the concentration of species, if any, previously present and emulsified in the droplet.
