Particle-assisted nucleic acid sequencing
First Claim
1. A method of sequencing a target nucleic acid, the method comprising:
- passing a microfluidic droplet containing a target nucleic acid through a microfluidic channel;
exposing the target nucleic acid to a plurality of particles, at least some of which have nucleic acid probes fastened thereto, wherein at least some of the particles are injected into said microfluidic droplet containing the target nucleic acid and said nucleic acid probes comprises a nucleic acid probe that can hybridize with said target nucleic acid; and
at least partially determining the sequence of the target nucleic acid based on binding of the particles to the target nucleic acid.

Abstract
This invention generally relates to particle-assisted nucleic acid sequencing. In some embodiments, sequencing may be performed in a microfluidic device, which can offer desirable properties, for example, minimal use of reagents, facile scale-up, and/or high throughput. In one embodiment, a target nucleic acid may be exposed to particles having nucleic acid probes. By determining the binding of the particles to the target nucleic acid, the sequence of the target nucleic acid (or at least a portion of the target nucleic acid) can be determined. The target nucleic acid may be encapsulated within a fluidic droplet with the particles having nucleic acid probes, in certain instances. In some cases, the sequence of the target nucleic acid may be determined, based on binding of the particles, using sequencing by hybridization (SBH) algorithms or other known techniques.
