Hollow polymer particles with dimensions in the submicrometer region possess great potential for encapsulation of large quantities of and large sized guest molecules into their empty core domains. Conventional molecular chemistry requires costly synthetic procedures and only in special cases allows such particles to be prepared with exact control over ...

Interleukin(IL)-12 is a protein that activates T cells and macrophages to kill tumor cells. However, despite this cytokine showing strong antitumor activity in preclinical settings, translation to patients has been slowed by toxic side effects, poor distribution to peripheral tissues, and improper dosing regimens.

Dynamics of Uranyl Peroxide Nanocapsules
Journal of the American Chemical Society, 2012Discrete aqueous metal oxide polyionic clusters that include aluminum polycations, transition-metal polyoxometalates, and the actinyl peroxide clusters have captivated the interest of scientists in the realm of both their fundamental and applied chemistries. Yet the counterions for these polycations or polyanions are often ignored, even though they are

Novel Long-Circulating Lipid Nanocapsules
Pharmaceutical Research, 2004To develop and evaluate novel long-circulating lipid nanocapsules (LN) designed for tumor delivery of lipophilic drugs.Nanocapsules were produced by a solvent-free phase inversion process and were coated with polyethylene glycoldistearoylphosphatidylethanolamine conjugate (DSPE-PEG) during preparation or by a post-insertion step.

NANOPARTICLES AND FILLED NANOCAPSULES
Carbon, 1995Encapsulation of foreign materials within a hollow graphitic cage was carried out for rare-earth and iron-group metals by using an electric arc discharge. The rare-earth metals with low vapor pressures, Sc, Y, La, Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er, Tm, and Lu, were encapsulated in the form of carbides, whereas volatile Sm, Eu, and Yb metals were not.

Optically switchable organic hollow nanocapsules
Journal of Colloid and Interface Science, 2010Hollow nanocapsules with both photoswitchable-fluorescent and reversible-photochromic properties are synthesized via a one-pot non-templating microemulsion copolymerization using methyl methacrylate and methacrylated spiropyran as co-monomers. The strong photoswitchable fluorescence of the nanocapsules are switched between "on" and "off" by alternating

Multifunctional metal-doped carbon nanocapsules
The Journal of Chemical Physics, 2008We present an ab initio study of carbon fullerenes, such as C20, C36, C56, C60, and C68, that are substitutionally doped with transition metals coordinated to several nitrogen atoms. These capsules with porphyrinlike metal sites have remarkable electronic and spin polarizations.

Nanofibrous photocatalysts from electrospun nanocapsules
Nanotechnology, 2017We present the design of multicompartment metal oxide/silica nanofibrous photocatalysts by colloid-electrospinning and subsequent calcination. During the calcination process, silica nanomaterials are cemented to form the fibrous framework and metal oxide precursors are crystallized inside and onto the fibers. This multicompartment nanofibrous structure,

Dimeric nanocapsule induces conformational change
Chemical Communications, 2010An induced cis-trans-trans (rctt) chair to cone structural rearrangement is forced by the addition of a pentacoordinate zinc(II) complex, overcoming thermodynamic and kinetic factors to produce the first phenyl-substituted zinc dimeric nanocapsule.

Magnetic {Mo72Fe30}-embedded hybrid nanocapsules
Journal of Colloid and Interface Science, 2009Magnetic nanocapsules were constructed by fabricating nanometer scaled C(60)-like "Keplerate" type {Mo(72)Fe(30)} with molecular formula [Mo(72)(VI)Fe(30)(III)O(252)(CH(3)COO)(12){Mo(2)O(7)(H(2)O)}(2){H(2)Mo(2)O(8)(H(2)O)}(H(2)O)(91)] x ca.150 H(2)O into nanocapsule shells using the LbL technique.
