| abstract |
Methods, systems, and devices are disclosed for fabricating and implementing nanoscale and microscale structured carriers to provide guided, targeted, and on-demand delivery of molecules and biochemical substances for a variety of applications including diagnosis and/or treatment (theranostics) of diseases in humans and animals. In some aspects, a nanostructure carrier can be synthesized in the form of a nanobowl, which may include an actuatable capping particle that can be opened (and in some implementations, closed) on demand. In some aspects, a nanostructure carrier can be synthesized in the form of a hollow porous nanoparticle with a functionalized interior and/or exterior to attach payload substances and substances for magnetically guided delivery and controlled release of substance payloads. |
