  • Publication number: 20150115487
    Abstract: Encapsulated solids are made by first encapsulating precursor materials in a polymer shell. The precursors are some combination of solids, liquids, gases, and/or gels. The precursors are then transformed into solids by emplacement of the capsule in an environment where gas or fluid transport into or out of the polymer shell causes transformation into solids.

    Abstract: The present invention provides a multi-component encapsulated reactive formulation comprising a mixture of two or more dry powder components, where each dry powder component is formed from a phase inversion process involving vigorous mixing. The dry powder is stabilized by hydrophobic colloidal particles, which assist in generating stable “dry water” microdroplets. One dry powder component comprises hydrophobic colloidal particles encapsulating microdroplets comprising an aqueous solution of one reactant, and the at least one other dry powder component comprises hydrophobic colloidal particles encapsulating microdroplets comprising an aqueous solution of another reactant. When the encapsulated formulation is agitated such that the encapsulates are broken, the encapsulates rupture and the two aqueous solutions undergo a reaction upon contact.

    Abstract: An apparatus for manufacturing a capsule by using vegetable gelatin is provided. Heating units are installed in a gelatin feeding line, which feeds gelatin in the form of a sheet, and a molding line to feed the gelatin in a predetermined temperature. The molded capsule is conveyed through a conveyer so that the molded capsule is stably dried and cured and a temperature of the conveyer is adjusted to control a temperature of the capsule. A length of the drying line is maximally increased within a narrow space, so that a film of the capsule made of the vegetable gelatin is gradually cured and dried without abrupt temperature variation, thereby preventing crack from occurring in the capsule, and preventing bonding parts of the capsule from being torn to improve the commercial value of the capsule.

The solution including a bioactive component and the lipid fraction, together with a carrier, is put in a reaction vessel, and a supercritical fluid is introduced thereto, so as to prepare particles coated with the bioactive component-lipid. The supercritical fluid is discharged by compression to obtain proliposome particles, and then the proliposome particles are hydrated by an aqueous solution including water so as to form a liposome solution. Preferably, the formulation may include one or more bioactive components. As required, the liposome formulation may be further processed by methods such as particle size reduction, removal of organic solvent, and freeze-drying. The preparation method can be easily carried out at a laboratory scale. Furthermore, the same method can be employed in liposome formulation preparation in mass production, or at a commercial scale.

    Abstract: A microfluidic system for creating encapsulated droplets whose shells can be further removed comprises: two electrode plates and a spacing structure disposed between the two electrode plates. One of the electrode plates has three reservoir electrodes and a plurality of channel electrodes. The three electrodes are respectively used for accommodating a shell liquid, a core liquid, and a removing liquid which is able to remove the shell liquid. The channel electrodes are used for communicating droplets among the three reservoir electrodes. Via these arrangements, the microfluidic system can create a quantitative shell droplet and a quantitative core droplet, and then merge the shell and core droplets to form an encapsulated droplet. Moreover, the shell of the encapsulated droplet can be removed by mixing it with the removing liquid. This invention is further provided with a method for creating an encapsulated droplet with a removable shell.

  • Publication number: 20120141796
    Abstract: A microfluidic device to produce polymersomes having three coaxial passageways of increasing size with fluid flowing in one direction. The first and smallest passageway contains the content of the polymersome, the middle passageway contains a block copolymer, and the largest and outer passageway contains an aqueous medium or water. The device can produce polymersomes with control of size and membrane thickness. The device will allow quantitative loading of the polymersomes in high quantities. The device is robust and easily assembled and has the ability to independently control the three streams involved in making the polymersomes.

  • Patent number: RE44508
    Abstract: The present invention is related to the production of capsules or particles of micro and nanometric size, for introduction into food, using stable electrified coaxial jets of two immiscible liquids with diameters in the micro and nanometric range. An aerosol of charged structured droplets forms when the jets dissociate by capillary instabilities. The structured droplets, which are mano-dispersed in size, contain a first liquid (generally the material desired to be added) that is surrounded by a second liquid. Generally the second liquid provides a barrier or protective coating which allows the addition of the first liquid to a food product without adversely affecting the organoleptic or other properties of the food product.
