Patent ID: 8709829

Claim:
A method for treating a condition comprising introducing into a subject in need of treatment at least one three-dimensional particle or biocapsule encapsulating a composition, wherein the three-dimensional particle or biocapsule comprises a plurality of two-dimensional faces capable of self-folding to form a hollow interior, wherein a size of the particle or biocapsule is microscale or nanoscale, and wherein the plurality of two-dimensional faces comprise a folding hinge between two adjacent faces and a locking or sealing hinge on an edge of a two-dimensional face, wherein the folding hinge between two adjacent faces has a width that is about twice a width of the locking or sealing hinge on an edge, wherein the plurality of two-dimensional faces comprising the three-dimensional particle or biocapsule are permanently held together by solid hinges; and wherein upon exposure of the three-dimensional particle or biocapsule to electromagnetic radiation or inductive heating, the composition is released through one or more pores within the particle or biocapsule into the subject in an amount sufficient to treat the condition.
