Research scientists at Georgia Tech have built nano-scale detectors so sensitive that they will be capable of spotting individual cancer cells.
The detectors are based on a new kind of quasi-one dimensional nano material, dubbed nanobelts or nanoribbons, which can be made from a variety of materials, like zinc or tin oxides. They are typically between 30nm and 300nm wide, and can be a few millimetres long.
The semiconducting nanobelts, first synthesised in 2001, can be tuned to exhibit certain behaviours. Introducing oxygen vacancies can affect their conductivity, surface and optical properties.

To tell the truth I'm not huge on the whole viridian thing but I'm into technology in a very large way. Specially Nanotechnology. The advances we can make in this area stagger the imagination.
