  • Publication number: 20130230452
    Abstract: A functional biologically active particle conjugate useful for diagnosis and treating cancer as a bioportal comprises a nanoscale particle having associated therewith an intracellular targeting ligand comprising a PNA, or another nuclease resistant oligonucleotide analog such as MOE-mRNA (2?-methoxyethyl mRNA) or LNA (locked nucleic acid), having a sequence that binds selectively to an uniquely expressed or overexpressed mRNA specific to the cancer or disease state in a living mammal. In one aspect the uniquely overexpressed target specific to the cancer or disease state is the unr mRNA which can be targeted by the antisense sequence PNA50.

  • Publication number: 20130210156
    Abstract: Described herein are optical agents, including compositions, preparations and formulations, for monitoring the pH of a fluid. Optical agents described herein include photonic nanostructures and nanoassemblies including supramolecular structures, such as shell cross-linked micelles, that incorporate at least one linking group comprising one or more photoactive moieties that provide functionality as exogenous agents for a range of pH monitoring applications. Optical agents described herein comprise supramolecular structures having linking groups imparting useful optical and structural functionality. In an embodiment, for example, the presence of linking groups function to covalently cross link polymer components to provide a cross-linked shell stabilized supramolecular structure, and also impart useful optical functionality, for example by functioning as a fluorophore.
