Core–shell microcapsules capable of regulating the release profile of encapsulated molecules are developed. These microcapsules uniquely embed miniature actuators in their liquid core. The internal actuators are made of stimuli-responsive smart hydrogel beads. The embedded hydrogel beads swell in response to external electric fields, regulating the internal pressure of the liquid core and thus the...
This paper report on a novel nano-electro-mechanical systems (NEMS) technology - nanoscale coaxial soft smart system (nCS3) that enables radial displacements of a multi-layered coaxial hollow fiber (CHF) and controlled modulations of a nanofluidic flow patterns inside the CHF responding to changes in local environments. The nCS3 has a unique nanostructure that consists of a liquid core and multiple...
