20140103553 | METHOD FOR FORMING MICROCAPSULES FOR ELECTROPHORESIS DISPLAY - An embodiment of the invention provides a method for forming microcapsules for electrophoresis display by forming microcapsules through a complex coacervation reaction between a sulfonated styrene maleic anhydride copolymer and gelatin, wherein a mass ratio of the sulfonated styrene maleic anhydride copolymer to the gelatin is 1:10˜10:1. The method of the embodiment of the invention not only can obtain microcapsules with good sealability and stability, but also can obtain microcapsules having evenly distributed particle sizes and low cost. | 04-17-2014 |
20140151912 | Virus/Nanowire Encapsulation within Polymer Microgels for 2D and 3D Devices for Energy and Electronics - Methods and apparatuses for encapsulating inorganic micro- or nanostructures within polymeric microgels are described. In various embodiments, viruses are encapsulated with microgels during microgel formation. The viruses can provide a template for in situ synthesis of the inorganic structures within the microgel. The inorganic structures can be distributed substantially homogeneously throughout the microgel, or can be distributed non-uniformly within the microgel. The inventive microgel compositions can be used for a variety of applications including electronic devices, biotechnological devices, fuel cells, display devices and optical devices. | 06-05-2014 |

20160144330 | Methods for Encapsulation of Actives within Droplets and other Compartments - The present invention generally relates to microparticles and, in particular, to systems and methods for encapsulation within microparticles. In one aspect, the present invention is generally directed to microparticles containing entities therein, where the entities contain an agent that can be released from the microparticles, e.g., via diffusion. In some cases, the agent may be released from the microparticles without disruption of the microparticles. The entities may be, for instance, polymeric particles, hydrogel particles, droplets of fluid, etc. The entities may be contained within a fluid that is, in turn, encapsulated within the microparticle. The agent may be released from the entity into the fluid, and then from the fluid through the microparticle. In such fashion, the release of agent from the microparticle may be controlled, e.g., over relatively long time scales. Other embodiments of the present invention are generally directed to methods of making such microparticles, methods of using such microparticles, microfluidic devices for making such microparticles, and the like. | 05-26-2016 |
