| abstract |
The present invention generally relates to droplet-based microfluidic devices, including systems, methods, and kits for amplifying or cloning within droplets. In some embodiments, the present invention is generally directed to systems, methods, or kits for amplifying a plurality of nucleic acids, e.g., without substantially selectively amplifying some nucleic acids over others. The nucleic acids may be contained within the droplets. In addition, in some embodiments, a plurality of microfluidic droplet containing a species of interest, such as a nucleic acid, may be mixed with microfluidic droplets free of the species, then pipetted or otherwise transferred such that, on average, a predetermined number of droplets containing species of interest is transferred. |
