Deoxyribonucleic acid (DNA) origami [1] is expected to be a nanoscale functional block for Nano Electro Mechanical Systems (NEMS). It can be assembled on a substrate containing other MEMS components to realize a NEMS device in which nanostructures play an important role. We recently demonstrated a tapping mode atomic force microscopy (AFM) process that can manipulate DNA origami structures in liquid...
Bovine insulin molecular aggregates, a nano-scale bio-entity, has been manipulated using P-NUVO (programmable nanomanipulation using vibration-mode operation AFM) method. This method uses the amplitude of an AFM cantileverpsilas vibration as real-time feedback information to detect the boundary of the nano-entities under manipulation. This amplitude signal changes as a function of the distance between...
A novel method is developed to effectively manipulating nano-entities to predefined positions and orientations autonomously. In this method, the nanomanipulation process is programmed by planning and executing the AFM tip's movement, and the amplitude of probe-tip's vibration is measured in real-time to detect the boundary of the nano-entities under manipulation - which will change as a function of...
A novel method based on vibration-mode of the atomic force microscope (AFM) for nanoimaging and nanomanipulation is introduced in this paper. With this approach, the amplitude of OMSPV (opto-electronic measurement signal of probe vibration) can be used as a feedback signal to detect and control the operation state under vibration-mode. By controlling the amplitude of AFM probe, the tip-sample interaction...
