Various embodiments provide materials and methods for synthesizing protocells for use in targeted delivery of cargo components to cancer cells. In one embodiment, the lipid bilayer can be fused to the porous particle core to form a protocell. The lipid bilayer can be modified with targeting ligands or other ligands to achieve targeted delivery of cargo components that are loaded within the protocell to a target cell, e.g., a type of cancer. Shielding materials can be conjugated to the surface of the lipid bilayer to reduce undesired non-specific binding.

Exemplary embodiments provide materials and methods for forming monodisperse particles. In one embodiment, the monodisperse particles can be formed by first spraying a nanoparticle-containing dispersion into aerosol droplets and then heating the aerosol droplets in the presence of a shell precursor to form core-shell particles. By removing either the shell layer or the nanoparticle core of the core-shell particles, monodisperse nanoparticles can be formed.

Various embodiments provide materials and methods of forming hollow cubes. The hollow cubes can be formed to include a metal oxide shell layer encasing a cubic hollow space. In one embodiment, the hollow cubes can be formed from an emulsion having aqueous droplets with an interfacial layer encasing an aqueous core. By an exemplary freezing treatment, the aqueous droplets having a spherical shape can be transformed into ice components having a cubic shape. Metal oxide precursors can then be added to react with the encased cube-shaped ice core at the interface with the interfacial layer to form a sol-gel metal oxide shell layer. Hollow cubes can be formed by removing the cube-shaped ice core from the sol-gel metal oxide shell layer.

A method of forming and resulting nano-structured composite includes atomizing a mixture of an amount of each of aminopropyltriethoxysilane, AgNO, DI water, and ethanol in a carrier gas; heating the atomized droplets at a selected temperature for a time sufficient to reduce the Ag to its elemental form in a silica matrix; and outputting the nano structured composite particles. A predetermined heating time is from about 0.01 to about 40 seconds and a selected heating temperature is from about 200 to about 800&#xb0; C. The nano structured composite includes a plurality of nano particles at a contact surface of the composite, dispersed throughout and at a contact surface of the composite, or dispersed throughout the composite.

In accordance with invention, there are methods for fabricating hollow spheres and nanofoams. The method for making hollow spheres can include providing a homogeneous precursor solution including a first solvent and one or more anhydrous precursor species and forming aerosol droplets having a first size distribution using the homogeneous precursor solution in an anhydrous carrier gas. The method can also include transporting the aerosol droplets through an aerosol reactor including a reactant to form a plurality of hollow spheres, wherein each of the plurality of hollow spheres can be formed by one or more chemical reactions occurring at a surface of the aerosol droplet. The method can further include controlling size and thickness of the hollow spheres by one or more of the precursor solution concentration, aerosol droplet size, temperature, residence time of the aerosol droplets in the aerosol reactor, and the reactant distribution in the aerosol reactor.
