| A method for the continuous production of a shaped hydrogel of absorbent resin is disclosed. This invention accomplishes the continuous production by continuously supplying in the form of a layer a monomer mixture capable of forming an absorbent resin by polymerization and polymerizing the layer of the monomer mixture. This method is characterized by retaining the rate of change of the thickness in the direction of width of the layer of hydrogel of absorbent resin at the time of formation of gel at a level of not more than 20%. The method is advantageously carried out by the use of an apparatus for the production of a shaped hydrogel of absorbent resin which comprises a movable endless revolving support belt, a monomer mixture supplying device, and a device for discharging the shaped hydrogel of absorbent resin, the apparatus preferably being provided near each of the opposite lateral parts of the movable endless revolving support belt with a lateral weir adapted to move in concert with the belt or being provided near each of the opposite lateral parts of the movable endless revolving support belt with a lateral weir fixed in such a manner as to contact the belt in a sliding state. The method of this invention permits production of a shaped hydrogel of absorbent resin intended to afford an absorbent resin which exhibits high absorption capacity, little water-soluble content and little residual monomer only in small amounts, and enjoys a high productivity rate. | ||||||

| 99 | Assays and other reactions involving droplets | US15449637 | 2017-03-03 | US09816121B2 | 2017-11-14 | Jeremy Agresti; Liang-Yin Chu; David A. Weitz; Jin-Woong Kim; Amy Rowat; Morten Sommer; Gautam Dantas; George Church |
| 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. | ||||||
