Title:
COLLOIDOSOME WITH TUNABLE, POROUS SHELL
Document Type and Number:
WIPO Patent Application WO/2019/191065
Kind Code:
A3
Abstract:
A colloidosome can include: a micro- or nano-structured porous shell comprising a plurality of micro- or nano-materials and interstices located between the micro- or nano-materials; and a core that is defined by the shell, wherein the shell is tunable to allow selective filling of an active material into the core and selective transport of the active material from the core through the shell. Methods of forming the colloidosome can include: combining micro- or nano-materials, a base fluid, and an active material to form a first fluid; adding a cross-linking agent to the first fluid to form a second fluid; and allowing the cross-linking agent to cross-link the micro- or nano¬ materials to form a micro- or nano-structured porous shell comprising a plurality of the micro- or nano-materials and interstices located between the micro- or nano-materials, and wherein the active material is located within a core that is defined by the shell.
