Abstract:
Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by placing a nanoparticle having a metallic shell on at least a fraction of a surface in a vicinity of a target structure in a subject and applying an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The nanoparticle is configured, upon exposure to a first wavelength λ1, to generate a second wavelength λ2 of radiation having a higher energy than the first wavelength λ1. The methods may further be performed by application of an initiation energy to a subject in situ to activate a pharmaceutical agent directly or via an energy modulation agent, optionally in the presence of one or more plasmonics active agents, thus producing an effect on or change to the target structure. Kits containing products or compositions formulated or configured and systems for use in practicing these methods.

Abstract:
The present invention comprises poly(vinyl benzoate) nanoparticle suspensions as molecular carriers. These nanoparticles can be formed by nanoprecipitation of poly(vinyl benzoate) in water using Pluronic F68 as surfactant, to create spherical nanostructures measuring about 200-250 nm in diameter which are stable in phosphate buffer and blood serum, and only slowly degrade in the presence of esterases. Kinetics experiments in phosphate buffer indicate that 78% of the coumarin-6 was encapsulated within the polymer matrix of the nanoparticle, and the residual 22% of coumarin-6 was surface-bound and quickly released. The nanoparticles are non-toxic in vitro towards human epithelial cells (IC50>1000 μg/mL) and primary bovine primary aortic endothelial cells (IC50>500 μg/mL), and exert non-observable bactericidal activity against a selection of representative test microbes (MIC>250 μg/mL). Poly(vinyl benzoate) nanoparticles are suitable carriers for molecular delivery of lipophilic small molecules such as drugs pharmaceutical and imaging agents.
