“…The ability of the AFM to image samples with minimal preparation in liquid environments has made it a particularly attractive tool for imaging biological samples [6], [7]. The most widely used application of the AFM is high-resolution imaging; however, adaptations of the AFM may be used to measure chemical [8], [9], magnetic [10], electrical [11], and material properties [12]. Other nonimaging applications of the AFM include probebased data storage [13]- [15], nanolithography [16], [17], and manipulation of single atoms and molecules [18].…”
