| abstract |
Certain aspects of the invention are generally directed to particles comprising a shell and an interior at least partially contained by the shell. In some embodiments, the particles may be treated to enhance the containment of the interior, for example to reduce transport of an agent into or out of the interior. Such particles may exhibit increased ability to encapsulate agents and/or increased storage life (e.g., due to reduced leakage). For instance, in certain embodiments, any defects, such as cracks, pores, etc. within the shell may be sealed or otherwise treated to reduce transport therethrough. In some embodiments, for instance, a first reactant in the interior of a particle may come into contact with a second reactant outside of the particle to form a solid, or other suitable product. The shell may also be treated to cause release of an agent contained within the interior, in certain aspects. |
