For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

The present invention generally relates to droplets and/or emulsions, such as multiple emulsions. In some cases, the droplets and/or emulsions may be used in assays, and in certain embodiments, the droplet or emulsion may be hardened to form a gel. In some aspects, a heterogeneous assay can be performed using a gel. For example, a droplet may be hardened to form a gel, where the droplet contains a cell, DNA, or other suitable species. The gel may be exposed to a reactant, and the reactant may interact with the gel and/or with the cell, DNA, etc., in some fashion. For example, the reactant may diffuse through the gel, or the hardened particle may liquefy to form a liquid state, allowing the reactant to interact with the cell. As a specific example, DNA contained within a gel particle may be subjected to PCR (polymerase chain reaction) amplification, e.g., by using PCR primers able to bind to the gel as it forms. As the DNA is amplified using PCR, some of the DNA will be bound to the gel via the PCR primer. After the PCR reaction, unbound DNA may be removed from the gel, e.g., via diffusion or washing. Thus, a gel particle having bound DNA may be formed in one embodiment of the invention.

Provided are methods for accelerated PCR wherein the amount of the amplified material is more than doubled within each of a plurality of successive cycles. The methods comprise the use of at least three primers and an incubation step at a sufficient temperature (acceleration temperature) that is less than an inter-cycle PCR denaturation temperature. In the invention embodiment, some target-specific primer extension products produced in a particular PCR cycle are amplified twice in each successive PCR cycle, once prior to incubating at the sufficient temperature, and once thereafter. Also provided are kits comprising at least three target-specific oligonucleotides configured to provide for accelerated PCR.
