摘要:
The present invention relates to systems and methods for sequencing nucleic acids, including sequencing nucleic acids in fluidic droplets. In one set of embodiments, the method employs sequencing by hybridization using droplets such as microfluidic droplets. In some embodiments, droplets are formed which include a target nucleic acid, a nucleic acid probe, and at least one identification element, such as a fluorescent particle. The nucleic acid probes that hybridize to the target nucleic acid are determined, in some instances, by determining the at least one identification element. The nucleic acid probes that hybridize to the target nucleic acid may be used to determine the sequence of the target nucleic acid. In certain instances, the microfluidic droplets are provided with reagents that modify the nucleic acid probe. In some cases, a droplet, such as those described above, is deformed such that the components of the droplets individually pass a target area.

The present invention generally relates to systems and methods for the control of fluids and, in some cases, to systems and methods for flowing a fluid into and/or out of other fluids. As examples, fluid may be injected into a droplet contained within a fluidic channel, or a fluid may be injected into a fluidic channel to create a droplet. In some embodiments, electrodes may be used to apply an electric field to one or more fluidic channels, e.g., proximate an intersection of at least two fluidic channels. For instance, a first fluid may be urged into and/or out of a second fluid, facilitated by the electric field. The electric field, in some cases, may disrupt an interface between a first fluid and at least one other fluid. Properties such as the volume, flow rate, etc. of a first fluid being urged into and/or out of a second fluid can be controlled by controlling various properties of the fluid and/or a fluidic droplet, for example curvature of the fluidic droplet, and/or controlling the applied electric field.

The present invention generally pertains to methods and kits for managing the variation in spectroscopic intensity measurements through the use of a reference component. The reference component may comprise a reference spectroscopic substance and may be contained together with a sample of interest in a sample to be tested, wherein the sample of interest may comprise a sample spectroscopic substance. Each sample to be tested may be uniquely identified and, hence, “barcoded” by combinations of different colors and concentrations of spectroscopic substances, contained therein.

The present invention generally pertains to a system for performing injection of multiple substantially controlled volumes into or out of a droplet, and methods and kits comprising the same. The system of the present invention comprises at least one microfluidic channel, one or more injection channels, an injection inlet associated with each of the one or more injection channels, and a mechanism for disrupting an interface between a droplet and a fluid and/or emulsion, wherein the at least one microfluidic channel comprises one or more droplets are flowing therein, and wherein each of the one or more injection channels comprises at least one fluid and/or emulsion therein.
