Colloidosomes: An Overview

Colloidosomes are fascinating structures formed by colloidal particles that self-assemble at the interface between two immiscible fluids, usually oil and water. These structures resemble hollow capsules or shells, with the colloidal particles tightly packed at the interface.

The original self-assembled structures are known as Pickering emulsions. The preparation of colloidosomes requires a mechanism of shell reinforcement at the interface to convert the Pickering emulsion precursor into a robust microcapsule that can survive the removal of the oil/water template.

Process of Colloidosomes Preparation

In general, the preparation of colloidosomes via Pickering emulsions involves three major steps.

1) The to-be-adsorbed nanoparticles are dispersed in the oil/water mixture to generate emulsification of two immiscible phases: oil-in-water (o/w) and water-in-oil (o/w) emulsions.

2) Subsequent interfacial reinforcement is required to crosslink the colloidal particles into robust microcapsules. In-situ covalent cross-linking with compatible cross-linkers at ambient temperatures allows for permanent stabilization of colloidosomes capable of surviving in different solvents without morphological distortion or fragmentation.

3) The emulsion-based fortified microcapsules are transferred to a continuous water phase via a process of dialysis or centrifugation for solvent exchange.
