“…The above-mentioned results indicated that wear of AFM tips on the mica substrates resulted in larger tip radius that provided a higher affinity (Boer-Duchemin et al, 2010;Daeinabi and Korayem, 2011;Korayem and Zakeri, 2011;Rao et al, 2009;Wang et al, 2008) to the DNA molecules to be picked up from surfaces. The increase of the tip radius after tip wear was proved by scanning electronic microscope (SEM) images (Fig.…”

“…Both methods would increase the radius of AFM tips, which is believed to result in a higher affinity (Boer-Duchemin et al, 2010;Daeinabi and Korayem, 2011;Korayem and Zakeri, 2011;Rao et al, 2009;Ternes et al, 2008;Wang et al, 2008) to the nanoobjects to be picked up. However, in the case of chemical coating, the coated AFM tip was easily damaged and the sample would be contaminated because AFM tip applied a relatively large force on the sample during nano-objects picking up operation.…”

The tip is one of the critical factors to improve the efficiency in picking up individual DNA molecules from solid substrates based on atomic force microscope (AFM) nanomanipulation. We found that wearing AFM tips on certain solid substrates in advance to nanomanipulation operation would largely improve the pickup efficiency, which was ascribed to the increasing affinity of the tip to the DNA molecules along with the increase of the tip radius after wearing. It was demonstrated that bare mica was superior to APTES-modified mica to keep the tip clean while wearing, which was crucial for DNA pickup during AFM nanomanipulation.

Since surface roughness greatly influences the force of adhesion between two bodies, the dynamic behavior of different biological micro/nanoparticles on rough surfaces during 3D manipulation operations has been studied in this paper by employing the atomic force microscope (AFM). In this regard, the force of adhesion between two surfaces has been simultaneously investigated on the basis of two important approaches. First, the interactions between two surfaces have been evaluated based on the available contact mechanics theories, and depending on the type of biological nanoparticle studied in this research, an appropriate model has been presented. Then, the common adhesion models of Rumpf and Rabinovich have been modified based on the Van der Waals force and with regard to the cylindrical geometry of the nanoparticles. Finally, based on the Schwartz method, by developing the adhesion model based on the two approaches mentioned above, the adhesion force between cylindrical biological nanoparticles and rough surfaces has been extracted for the first time. The dynamic behavior of nanoparticles in 3D manipulation on a rough substrate has been modeled and then simulated and analyzed. The simulation results indicate that, by increasing the asperity radius, the critical force needed to manipulate a nanoparticle increases. Also, in contrast to the sliding mode, the critical force of movement in the rolling mode diminishes with the increase of nanoparticle radius. The experimental results obtained from the topography of glass and silica substrates indicate that the Rumpf model underestimates the adhesion force relative to the Rabinovich model.
