Manipulating Single Nano-objects with Dynamic Temperature Fields
Prof. Frank Cichos, Institute of Experimental Physics I, Universität Leipzig
One of the challenges of single molecule experiments in solution is the ability to localize and manipulate one or even multiple molecules. To do so a driving mechanism is required which is able to control the Brownian fluctuations of the nano-objects. Here we discuss experiments, which employ the “fuel” of Brownian fluctuations – temperature - to push nano-objects. Combined with optical feedback mechanisms effective potential landscapes can be shaped to store and manipulate single or even a well-defined number of multiple objects in a small observation volume. The paves the way for extended single molecule studies in solution or even well controlled bi- or multi molecular interaction studies.
