To perform near-field optics and thermics, we use a fluorescent particle glued at the end of a sharp tip. The particle acts as a nanodetector of light or as a nanothermometer. In order to fabricate these tips, we have developed several micro and nanomanipulation systems composed of several piezoelectric displacement modules. One of the system is operating at ambiant atmosphere under a classical optical microscope. We have also performed some nanomanipulations in a Scanning Electron Microscope.
The tips are coated with a thin adhesive polymer layer, and brought in contact with a surface on which the particles are deposited. With piezoelectric stacks, we manually move the tip on a particle that remains sticked at its end (see Fig. 1 for an example). The images in Fig. 2 illustrate the picking of a gold particle by a tip, in-situ inside a SEM. The tip is moved with a 3D piezoelectric stage.
SEM pictures of fluorescent nanoprobe tips are shown in Fig.3.
