By real-time object tracking and control of the position of the heating laser focus, we can precisely employ thermophoretic drift to oppose the random diffusive motion. As a result, a nano-object is confined in a micrometer-sized trap. Numerical

For the creation of high thermal gradients, their approach requires prefabricated plasmonic structures, which results in a big drawback: the confinement of an object is possible just within the structure, i.e., the object can not be freely

The combination of several instruments is thus necessary to metrologically characterize the dimensional properties of a nano-object. This paper
