The PICASSO experiment is searching for cold dark matter through the direct detection of weakly interacting massive particles (WIMPs), in particular neutralinos (χ) via their spin-dependent interactions with nuclei. The experiment is installed in the Sudbury Neutrino Observatory Laboratory at a depth of 2070 m (6000 mwe). PICASSO makes use of the superheated droplet technique with C4F10 as the active material, and searches for χ interactions on 19F. The results of these measurements are presented in terms of limits on the spin-dependent χ-proton and χ-neutron cross sections. Limits on the effective χ-proton and χ-neutron coupling strengths ap and an are also reported. The results exclude new regions of the spin-dependent χ-nucleon interaction parameter space. The next phase of PICASSO is briefly discussed.
