Description
Summary:An inside job: Porous hollow carbonaceous microspheres can be easily fabricated by hydrothermal treatment of Saccharomyces cerevisiae cells. An amphiphilic surface and porous shell structure endow these microspheres with phase‐transfer features and the ability to enrich proteins inside their hollow interiors. These characteristics will enable their application in drug delivery, active ingredients encapsulation, adsorption, and separation techniques.
