摘要:Topical skin compositions include a complex containing components to provide a defense against the various pathway mechanisms of free radicals, reactive oxygen species, reactive nitrogen species, and other oxidizing species on the human body including the skin. The compositions may be administered by topically applying them in an amount to inhibit those mechanisms. The compositions and methods are directed to the prevention of the adverse or detrimental effects of free radicals, reactive oxygen species, reactive nitrogen species, and other oxidizing species on the human body including the skin. Thus, the compositions according to the invention improve barrier function, inhibit elastase and collagenase, and/or promote synthesis of collagen and elastin.

标题:Molecular compounds having complementary surfaces to targets

摘要:Synthetic polymer complements (SPCs) are provided, as well as methods for their synthesis and use. The SPCs may have surfaces that include functional groups that are complementary to surface sites of targets such as nanostructures or macromolecular targets, and may be capable of specifically interacting with such targets. The positions of the functional groups in one embodiment are stabilized by a polymer network. The SPCs are formed by contacting the target with a set of monomers which self-assemble on the target, and then are polymerized into a network to form the synthetic polymer complement. At least a portion of the surface of the resulting SPC thus may include an imprint of the target. The complex of the SPC and the target may be the desired product. Alternatively, the target is released, for example, by controllably expanding and contracting the crosslinked network. The SPC is isolated and used in many applications.
