Fabrication of coupled graphene-nanotube quantum devices.

We report on the fabrication and characterization of all-carbon hybrid quantum devices based on graphene and single-walled carbon nanotubes. We discuss both carbon nanotube quantum dot devices with graphene charge detectors and nanotube quantum dots with graphene leads. The devices are fabricated by chemical vapor deposition growth of carbon nanotubes and subsequent structuring of mechanically exfoliated graphene.

[Subretinal transplantation of confluent pigment epithelium: a novel device for non-traumatic tissue handling].

Background: Subretinal transplantation of pigment epithelium may be a therapeutic option in the treatment of age-related macular degeneration. Suspensions of pigment epithelial cells as well as confluent cell layers are being considered.

Methods: We developed a surgical device which permits to load living tissue, without exerting mechanical stress to the cells themselves, and to deliver it precisely onto the subretinal target site.

[Endoscope-assisted fixation of condylar fractures of the mandible].

The reduction and plate osteosynthesis of condylar fractures often require a wide extraoral approach with the risk of facial nerve palsy. The endoscopic technique is an alternative. Seven condylar fractures were operated on under endoscopic control.
