Caged Colloids

Colloidal microcontainers, such as hollow capsules and colloidosomes, have a range of applications, including drug delivery, energy storage, artificial protocells. In this study, we present versatile scalable self-assembly approach for encapsulating cargo particles within well-defined porous membranes or cages. The encapsulation process involves camouflaging liquid matrix that serves scaffold satellite to form densely packed shells around. These satellites fuse create self-standing cages, after which the is dissolved, trapping inside. By adjusting fusion protocol, can control porosity cages at various length scales. We demonstrate potential technique by employing functional showcase transmembrane transport phenomena, delivery active uptake nanoparticles.
