A facile approach for the preparation of crosslinked polymeric nanocapsules was developed by the combination of the surface-initiated atom transfer radical polymerization and ultraviolet irradiation crosslinking techniques. The well-defined polystyrene grafted silica nanoparticles were prepared via the SI-ATRP of styrene from functionalized silica nanoparticles. Then the grafted polystyrene cha...
Unbalanced western-style diet and a sedentary lifestyle are increasingly recognized as important contributors to the observed increase in obesity and chronic diseases in the western world. Supplementing foods with health promoting bioactive ingredients poses a major technological challenge since some of these constituents, like omega-3 poly-unsaturated fatty acids (PUFA), exhibit poor chemical ...
A one-pot solvothermal process has been developed for direct preparation of PdCu nanocapsules (with a size of ca. 10 nm) on three-dimensional (3D) graphene. Due to the 3D pore-rich network of graphene and the unique hollow structure of PdCu nanocapsules with a wall thickness of ca. 3 nm, the newly-prepared PdCu/3D graphene hybrids activated electrochemically have great electrocatalytic activity...
The assessment of tumor oxygenation is a crucial factor in cancer therapy and may be carried out using fluorine MRI once fluorine probes have been distributed within the tumor. However, the deposit of those highly fluorinated compounds often jeopardizes anatomical image quality and requires emulsification of the probes. Due to the high density and the high lipophilicity of perfluorocarbons, nan...
Graphitic carbon nanocapsules, nanosheets and nanoplates were selectively obtained via a solid-state pyrolysis route from various ion-exchange resin-iron complexes.
BACKGROUND Modifications of adjuvants that induce cell-mediated over antibody-mediated immunity is desired for development of vaccines. Nanocapsules have been found to be viable adjuvants and are amenable to engineering for desired immune responses. We previously showed that natural nanocapsules called vaults can be genetically engineered to elicit Th1 immunity and protection from a mucosal bac...
Polymeric nanomaterials are deemed to unlock the potential of therapeutics and improve their efficiency, allow future advances in nanomedicine. Among these, sugar-based nanocapsules made synthetic or natural carbohydrate-based macromolecular chains have raised significant interest bio-applications. This review highlights physical or/and chemical techniques construct both water- oil-filled nanoc...
