There is plenty of indirect evidence that a large fraction of the energy
content of the Universe is made from a yet unknown form of dark matter.
The XENON100 experiment, installed underground in the Laboratory
Nazionali del Gran Sasso (LNGS, Italy), is searching for WIMP dark
matter particles scattering off a large liquid xenon target. XENON100
features the lowest background of all running dark matter experiments
and has recently published the results of 225 live days of data taking:
No indication for a dark matter signal has been found, therefore leading
to the strongest limits on WIMP-nucleon scattering cross sections to-date.

In this talk, I will introduce the experiment and focus on the recent
results. Finally, the status of the successor experiment XENON1T, which
aims at a sensitivity increase in 2 orders of magnitude, will be presented.
