Appl. No.:

12/440715

International Classification:

A61K 51/00
A61K 51/12

US Classification:

424 129

Abstract:

Novel phototherapeutic methods and compositions are described herein. Nanoparticle-assembled microcapsules as a new type of delivery vehicle for photosensitive compounds may be synthesized through a two-step assembly process. Charged polymer chains and counterions may be combined with a photosensitive compound to form photosensitive aggregates, and then nanoparticles may be combined with the aggregates to form the microcapsules. The shell may be composed of nanoparticles and/or polymer, and the core interior may contain the photosensitive compound. Formation occurs rapidly (on the order of seconds) and the conditions are very mild (at room temperature, in aqueous solution, and at neutral pH). The microcapsule synthesis is highly suitable as an encapsulation method, particularly for a charged photosensitive molecule like ICG.

Abstract:

Compositions containing a transporter component and a signaling component and a method for using said compositions for analyzing porous media and flowing liquid streams, specifically for measuring pressure, temperature, relative abundance of water, pH, redox potential and electrolyte concentration. Analytes may include petroleum or other hydrophobic media, sulfur-containing compounds. The transporter component includes an amphiphilic nanomatenal and a plurality of solubilizing groups covalently bonded to the transporter component. The signaling component includes a plurality of reporter molecules associated with the transporter component. Said reporter molecules may be releasable from the transporter component upon exposure to at least one analyte. The reporter molecules may be non-covalently associated with the transporter component, or the reporter molecules are covalently bonded to the transporter component. Furthermore, said compositions and methods may be used to actively enhance oil recovery and for remediation of pollutants.
