Manipulations of individual molecules by scanning probe microscopy

TL;DR

This paper introduces a novel scanning probe microscopy technique for manipulating individual molecules through a controlled pick-up-and-put-down method, enabling precise control over molecule transfer by adjusting tip parameters.

Contribution

The paper presents a new manipulation method for single molecules using scanning probes, with control over molecule transfer based on tip velocity and approach distance.

Findings

Controlled molecule pickup and deposition demonstrated.

Manipulation efficiency depends on tip velocity and proximity.

Potential for precise nanoscale molecular assembly.

Abstract

In this Letter we suggest a new method of manipulating individual molecules with scanning probes using a "pick-up-and put-down" mode. We demonstrate that the number of molecules picked up by the tip and deposited in a different location can be controlled by adjusting the pulling velocity of the tip and the distance of closest approach of the tip to the surface.
