Raw data underlying the publication: 'The Motion Of Catalytically Active Colloids Approaching A Surface'

We looked at the motion of catalytically active particles and studied the influence of salt concentration on the motion for colloids moving at different separation distances from a wall. This dataset consist of the particle traces (polystyrene of 4.5 micron in diameter, half-coated with 5 nm Pt/Pd) separated in three main folders.'microscope_without_acoustic_tweezers' consists of particle traces of 2D experiments, where the particles sedimented and moved parallel to the substrate. The different subfolders specify the fuel concentration (hydrogen peroxide) and the salt concentration (sodium chloride).'microscope_with_acoustic_tweezers' consists of particle traces of 3D experiments, where the particles where lifted using acoustic tweezers and propelled in 3D.'microscope_with_tilted_stage' consists of particle traces of 2D experiments, where the particles moved on a tilted substrate (the subfolders indicate the tilt angle with respect to the horizontal).
