  • Publication number: 20180272042
    Abstract: A polymer film coating for medical devices and medical devices with coating are provided to controllably release one or more therapeutics or other agents locally at the tissue-device interface for a prolonged period of time. The coating can be prepared via layer by layer (LbL) assembly of polymers and/or polymers conjugated to or otherwise associated with one or more drugs, particularly recyclable antioxidants or antioxidant regulators. The resulting coating contains alternating layers that are assembled via electrostatic interactions, hydrogen bonding, or other secondary interactions. The coated device can provide for long term local delivery of antioxidants, preferably antioxidant upregulators and/or recyclable antioxidants, to modulate the oxidative stress associated with brain implants.

  • Publication number: 20040067163
    Abstract: A sensor comprising at least one photonic crystal, at least one light source capable of illuminating the crystal with a light beam having a predetermined wavelength and direction, and at least one position sensing detector positioned so as to detect the position of said light beam after it is transmitted by the crystal. Sensing is achieved by saturating the crystal with a liquid so as to produce a saturated crystal having a first refractive index, calculating for the crystal a dispersion surface and using the dispersion surface to calculate a effective incident light vector; and illuminating the saturated crystal with at least one light beam, the beam being incident substantially along the calculated effective incident light vector such that if the saturated crystal is modified to have a second refractive index, the position-sensing detector will detect a change in position of the transmitted light beam.

  • Patent number: 5537000
    Abstract: An electroluminescent device is described, as well as a method of making same, wherein the device is characterized by a semiconductor nanocrystal electron transport layer capable of emitting visible light in response to a voltage applied to the device. The wavelength of the light emitted by the device may be changed by changing either the size or the type of semiconductor nanocrystals used in forming the electron transport layer. In a preferred embodiment the device is further characterized by the capability of emitting visible light of varying wavelengths in response to changes in the voltage applied to the device.
