    • This invention is directed to a new composition of matter in the form of chemically derivatized silica coated fullerenes, including silica coated C60 molecules and silica coated carbon nanotubes, processes for making the same and to uses for the derivatized silica coated fullerenes. Included among many uses in chemical, physical or biological fields of use, but not limited thereto, are high speed, low loss electrical interconnects for nanoscale electronic devices, components and circuits. In one embodiment, this invention also provides a method for preparing silica coated fullerenes having substituents attached to the surface of silica coated fullerenes by reacting silica coated fullerenes with a wide range of organic or inorganic chemical species in a gaseous or liquid state. Preferred substituents include but are not limited to organic groups and organic groups containing heteroatoms such as oxygen, nitrogen, sulfur, and halogens. The identity of the surface functional group is chosen to provide desirable properties to the silica coated fullerenes including but not limited to solubility, miscibility, stickiness, and melting point. The present invention also describes the application of surface functionalized silica coated fullerenes as components of polymer blends and composites.

    • A retinal implant can include an array of photoreceptors adapted for positioning in the eye. Each photoreceptor can include a core, for example a carbon nanostructure, and a shell. The shell can include a light-responsive layer, and in many cases, the light-responsive layer can be formed of two semiconductor layers forming a heterojunction. The photoreceptors can be adapted to generate an electric field in response to incident light so as to stimulate a retinal neuron in its vicinity. The photoreceptors can be micron-sized or nano-sized, and can be arranged in densities similar to the density of rods and cones in the human eye. In one embodiment, an exemplary sensor for an imaging device can include a plurality of photosensors disposed on a substrate. Each photosensor can include a carbon nanostructure, a light-responsive layer coating at least a portion of the carbon nanostructure.
