  • Publication number: 20130171207
    Abstract: The invention provides active agents, such as paclitaxel, rapamycin, or 17-DMAG, encapsulated by safe poly(ethylene glycol)-block-poly(lactic acid) (“PEG-b-PLA”) micelles. The compositions provide effective solubilization of drug combinations, such as paclitaxel, rapamycin, and 17-DMAG, as well as others described herein. A significant advantage of PEG-b-PLA as a carrier is that it is less toxic than Cremophor® EL or DMSO, which are used in currently known compositions. Additionally, PEG-b-PLA micelles are easier to handle than DMSO and they do not possess a foul odor, which is a problem with formulations currently in clinical trials. Accordingly, the invention provides stable and biocompatible drug formulations that improve bioavailability without causing toxicity. It was also found that larger doses of individual drugs in micelle formulations can be administered compared to non-micelle formulations.

  • Patent number: 8470946
    Abstract: Carbon nanotube (CNT) yarns and sheets having enhanced mechanical strength using infused and bonded nano-resins. A CNT yarn or sheet is surface-activated to produce open bonds in the CNT walls prior to resin infusion. The CNT yarn or sheet is infused with a low viscosity nano-resin that penetrates spaces between individual CNTs and is cured to cross-link and chemically bond to the CNT walls, either directly or through a functional molecule, to bond the individual CNTs or ropes to each other. The nano-resin can comprise dicyclopentadiene having an uncured viscosity near that of water. The cross-linking process involves ring-opening metathesis polymerization and catalysis of the nano-resin in combination with a functionalizing material such as norbornene, to enhance bonding between the carbon and nano-resin. The process increases load capability, tensile strength, and elastic modulus of the yarns and sheets, for use as a structural component in composite materials.

Other nanosized drug delivery vehicles such as dendrimers, micelles, nanocapsules and nanoparticles may be similarly coated with anti-TNF-a antibody and used to deliver the drug to the site of inflammation. Also in lieu of the anti-TNF-a antibody other TNF-a binding agents such as aptamers and binding peptides may be used to coat the various nanosized drug delivery vehicles such as micelles, dendrimers, nanocapsules and nanoparticles in order to deliver the drug to the site of inflammation.

  • Patent number: 8394393
    Abstract: A composite material containing polymeric nanofibers, themselves containing NO-donor molecules, imbibed with an elastomer matrix is permeable to both water and gas so that dissociation reactions in the presence of water releases NO gas in a sustained manner. The NO-donor nanofibers may be formed by synthesizing acceptable NO-donor molecules, blending such molecules in solution with PVP, PCL or PVAc, electrospinning the blend at relatively high voltage for form fiber mats, applying PDMS rubber to the fiber mat and crosslinking it. The resulting NO-releasing electrospun fiber composite may be used in medical devices such as catheters, stents, or vascular grafts, with the purpose of releasing nitric oxide within a controlled rate and for a sustained period of time, as well as other known medical applications for NO.
