Recently, we proposed a new probe-based manipulation technique, namely, vibrational nanoplacing, which reduces the requirements on the substrate flatness. The new manipulation scheme relies on adhesion forces to capture a sample at the nanoscale and transport it. The sample is then released using dynamic oscillations of the probe. In the present paper, we analyze the generalization of the proposed approach to multisamples and investigate selective release.
