Proposed a bubble propulsion mechanism stemming from momentum change induced by the detachment of O2 bubbles to explain the locomotion of disk-like Au-Ni-Pt nanoswimmers in diluted H2O2 solution.
- class="label">•
Investigated the generation and detachment of O2 bubbles from Pt-surface.
- class="label">•
Explored the relationship between the motion speeds of disk-like Au-Ni-Pt nanoswimmers and the temperature of the diluted H2O2 solution.
- class="label">•
Characterized the propulsion of Au-Ni-Pt nanoswimmers in either a circular or a translational way, depending on the presence of a torque or not.
