A quantum dot microscope apparatus is provided. A further aspect employs a tilted or tapered end or tip on a microscopic probe. Another aspect of the present apparatus employs a probe including a quantum dot with only one tunneling lead connected to a power source. A manufacturing aspect includes creating a tapered or asymmetrically shaped specimen-facing end of a probe where a quantum dot is located on the end. A further manufacturing aspect includes using focused ion-beam milling to create a tip or end of a quantum dot microscope probe.

A nanowire comprising a purified protein filament, such as a pilus, isolated from a bacterium, such as, is provided. Such a purified pilus can contain peptide subunits capable of assembling into the protein filament and establishing an electrical connection with an insoluble electron acceptor. The novel nanowires can be produced via a novel single step. Such nanowires are useful in applications requiring rectifying behavior.
