摘要： The present disclosure relates to a composition comprising a shell surrounding a core, wherein the core comprises one or more lyophilised microspheres. Also described herein is a method comprising providing one or more lyophilised microspheres; and coating the one or more lyophilised microspheres with a shell under conditions effective to encapsulate the one or more lyophilised microspheres. The present disclosure further relates to a system comprising one or more composition as described herein, and one or more lyophilised cake, wherein the one or more composition and the one or more lyophilised cake are combined under conditions effective to form a rehydration system. Also described herein is a method of controlling release of one or more encapsulated microspheres comprising providing a composition as described herein and mixing the composition with a rehydration solution under a first condition effective to control release of one or more lyophilised microspheres from the composition.

摘要： The present disclosure relates to compositions including a shell surrounding an interior compartment, wherein said interior compartment comprises one or more reagent and wherein said shell releases said interior compartment when said shell is exposed to a first release condition, wherein said interior compartment releases said one or more reagent when said interior compartment is exposed to a second release condition, and wherein said first release condition is different from said second release condition. Also disclosed are compositions including a dissolvable first shell, and a dissolvable second shell, the second shell comprising one or more reagent. Also disclosed are methods for controlling release of one or more reagent using the compositions described herein. The present disclosure further relates to cartridges that include a reagent reservoir including the compositions described herein. Also disclosed are systems for controlling release of one or more reagent including the compositions described herein.

摘要： The present disclosure relates to a method including exposing a composition comprising a wax-microsphere matrix to a first melt-condition, wherein said wax-microsphere matrix comprises a wax component and a plurality of lyophilised microspheres, wherein said plurality of lyophilised microspheres comprise one or more reagent, whereby exposing said composition comprising said wax-microsphere matrix to said first melt-condition melts the wax component; exposing said composition to a first release-condition to rehydrate at least one lyophilised microsphere; and exposing said at least one rehydrated lyophilised microsphere to a separation-condition to separate said wax component from said at least one rehydrated lyophilised microsphere. Also disclosed are methods of preparing a wax-microsphere matrix and releasing one or more reagent from a wax-microsphere matrix as well as compositions. Also disclosed are cartridges with a reagent reservoir including the compositions described herein. Also disclosed are systems for controlling release of one or more reagent including the compositions described herein.

摘要： The present disclosure relates to a method, including providing one or more lyophilised microspheres in a mixing vessel at a first temperature and generating a fluidized bed of the one or more lyophilised microspheres in the mixing vessel, under conditions effective to encapsulate the one or more lyophilised microspheres with a coating formulation. In an example, the fluidized bed has a fluidization rate of between about 1 cubic meters per hour (m3/h) and about 30 m3/h. In another example, the fluidized bed has an environmental humidity of between about 10% and about 20%. In still another example, the coating formulation is applied at a spray rate of between about 1.5 grams per minute (g/min) and about 10 g/min. In yet another example, the coating formulation is applied at an atomizing rate of between about 0.5 bar and about 1.5 bar. In a further example, the fluidized bed is in a Wurster configuration, a top spray configuration, or a combination thereof. The present disclosure also relates to a system, including one or more lyophilised microspheres, a mixing vessel configured for holding the one or more lyophilised microspheres, a mixer for generating a fluidized bed of the one or more lyophilised microspheres in the mixing vessel at a location, and at least one spray nozzle configured to introduce a shell formulation into the mixing vessel at the location.
