Tiny capsules with different substances on their surface could be useful in medicine and materials technology

Hollow capsules that have a selectively permeable shell are promising candidates as tiny containers for molecules, particles or bubbles, and are becoming increasingly important in a wide variety of applications. But making these kinds of capsules with more than one kind of substance on their shells has been challenging – until now.

Hollow capsules with two or more substances on their surface are able to organize themselves in specific ways, which means they could be used to grow human skin or other body tissues, or to make porous tissues and composites. They can also be used to transport a variety of substances and release them in specific environments.
