    摘要: The present invention provides matrixes doped with semiconductor nanocrystals. In certain embodiments, the semiconductor nanocrystals have a size and composition such that they absorb or emit light at particular wavelengths. The nanocrystals can comprise ligands that allow for mixing with various matrix materials, including polymers, such that a minimal portion of light is scattered by the matrixes. The matrixes of the present invention can also be utilized in refractive index matching applications. In other embodiments, semiconductor nanocrystals are embedded within matrixes to form a nanocrystal density gradient, thereby creating an effective refractive index gradient. The matrixes of the present invention can also be used as filters and antireflective coatings on optical devices and as down-converting layers. The present invention also provides processes for producing matrixes comprising semiconductor nanocrystals.

    摘要: An antimicrobial coating system and method are described. In some embodiments, a system may include a composition. The composition may include one or more bridged polycyclic compounds. At least one of the bridged polycyclic compounds may include at least two cyclic groups, and at least two of the cyclic groups may include quaternary ammonium moieties. In some embodiments, a method may include applying an antimicrobial coating to an oral surface, a surface of a construction substrate, a surface of a marine substrate, a surface of a medical device, or a surface of a personal care device. The protective coating may be antimicrobial. A protective coating may include antimicrobial bridged polycyclic compounds. Bridged polycyclic compounds may include quaternary ammonium compounds. Bridged polycyclic compounds based coating systems may impart self-cleaning properties to a surface (e.g., a tooth surface).

    摘要: A prosthetic retina for implantation in an eye having a defective retina is formed from an array of nanowires having a predetermined spatial distribution, density, size and shape implanted in close proximity to the retina. An electrical conductor is formed at a first end of all nanowires in the array of nanowires and placed in contact with a bias source which biases the array. A plurality of electrodes is located on a second end of each of one nanowire or a bundle of nanowires in the array. Each nanowire produces a photocurrent at a corresponding electrode in response to detection of light impinging on the array of nanowires and the photocurrent stimulates one or more neurons adapted for visual perception. In the preferred embodiment, the predetermined spatial distribution mimics a distribution of rods and cones in a normal eye.
