The size of an atomic force microscopy tip-top is evaluated by the measurement of desoxyribonucleic acid under atomic force microscopy. The cross section of desoxyribonucleic acid images gives the information about a tip, based on the analysis on the formation of an image under atomic force microscopy. The elements of tip images at different directions are collected and combined to form the top 2 nm tip image. The possible error of tip size determined by this method is analysed. The minimum size of feature on a sample, which could be detected by atomic force microscopy, is discussed based on the tip image.
