F/col STM image of DNA
Numéro d’image : 11817721
| False-colour scanning tunnelling micrograph (STM) of DNA. A sample of uncoated,double-stranded DNA was dissolved in a salt solution & deposited on graphite prior to being imaged in air by the STM. An STM image is formed by scanning a fine point just above the specimen surface & electronically recording the height of the point as it moves. The main feature of this image is a right-handed,double-stranded DNA molecule (a DNA duplex),which appears as the row of orange/yellow peaks at centre-left. These peaks correspond to the ridges of the DNA double helix. Magnification: x1,600,000 at 6x7cm size | |
