A process is provided for releasably encapsulating a biological entity. The process comprises combining a solution of a surfactant in a non-polar solvent with a precursor material and the biological entity to form an emulsion. The emulsion comprises a polar phase dispersed in a non-polar phase, wherein the polar phase comprises the biological entity. The particles comprising the biological entity are then formed from the polar phase.

Controlled release of biological entities

A process for preparing particles having a hydrophobic material therein is disclosed. The process comprises providing a multiple emulsion comprising a first emulsion dispersed in a hydrophobic medium, said first emulsion comprising a hydrophobic phase dispersed in a hydrophilic phase, wherein the hydrophobic phase comprises the hydrophobic material and the hydrophilic phase comprises a precursor which is capable of reacting to form a non-fluid matrix and reacting the precursor in the multiple emulsion to form the matrix in the form of the particles having the hydrophobic material therein wherein the precursor is added prior to formation of the multiple emulsion. Also disclosed are particles having a hydrophobic material therein, which may be releasable, as well as particles having a hydrophobic material therein, which may be releasable, made by the process and methods of using the particles.

Particles having hydrophobic material therein

A method is described for delivering a species to a liquid, whereby porous particles are exposed to a condition such that the species is rapidly released into the liquid. Each of the porous particles comprises an agglomeration of primary particles so that outer surfaces of said primary particles define pores of said porous particles. The primary particles comprise silica and the species is disposed in the pores of the porous particles.

Triggered release

A process for making particles comprising a hydrophobic dopant for subsequent release therefrom is disclosed. The process comprises providing an emulsion comprising a hydrophilic phase and a hydrophobic phase dispersed in the hydrophilic phase, and reacting the precursor material to form the particles comprising the dopant therein. The hydrophobic phase comprises a precursor material and the dopant.

Particles comprising a releasable dopant therein

A process is provided for releasably encapsulating a biological entity. The process comprise combining a solution of a surfactant in a non-polar solvent with a precursor material and the biological entity to form an emulsion. The emulsion comprises a polar phase dispersed in a non-polar phase, wherein the polar phase comprises the biological entity. The particles comprising the biological entity are then formed from the polar phase.

The invention provides a membrane comprising a gel reinforced by a support. The membrane has opposing surfaces and a thickness between said surfaces. The gel communicates between the opposing surfaces and allows diffusion of a nutrient solution through the membrane. A bioreactor is also provided, comprising a membrane-supporting structure, and a membrane according to the invention supported on the membrane-supporting structure.
