    Abstract: The invention provides a composition comprising core-shell nanoparticles, the nanoparticles comprising
    (a) cationic core material comprising polymer; and
    (b) a shell material comprising silica.
    Preferred core materials comprise diblock copolymer micelles comprising one block of dialkylaminoethyl methacrylate units which are partially or fully quaternised and one block of dialkylaminoethyl methacrylate units that remain non-quaternised .
    The invention also provides a method for the preparation of the said composition, the method involving
    (a) preparing a cationic core material comprising polymer; and
    (b) coating the core material with a shell comprising silica by treating the polymer with a silica precursor under ambient conditions.
    The invention also envisages a composition comprising core-shell nanoparticles which is adapted to facilitate controlled delivery of at least one active agent into a system in response to controlled changes in the pH of the system.

    Abstract: Various embodiments disclosed relate to melt-stabilized materials including ultra high molecular weight polyethylene (UHMWPE), methods of making the same, and medical implants including the same. In various embodiments, the present invention provides a method of melt-stabilizing a material including UHMWPE. The method includes obtaining or providing a solid material including UHMWPE including a first concentration of free-radicals. The method includes coating at least part of the solid material with a liquid composition including at least one antioxidant, to provide a coated solid material. The method includes heating the coated solid material in an environment including oxygen, the heating being sufficient to melt at least part of the UHMWPE, to provide a heated material. The method also includes solidifying the heated material, to provide a melt-stabilized material including UHMWPE including a second concentration of free-radicals, wherein the second concentration of free-radicals is less than the first concentration of free-radicals.
