Abstract

Methods, structures, devices and systems are disclosed for fabricating and implementing nanoparticles with hollow core and sealable holes. In one aspect, a nanoparticle device can includes a shell structure including at least two layers including an internal layer and an external layer, the internal layer structured to enclose a hollow interior region and include one or more holes penetrating the internal layer, the external layer is of a porous material and formed around the internal layer and sealing the one or more holes, and a substance contained within the hollow interior region, the substance incapable of passing through the external layer.
