Sketch shows the 3D nanostructured sample with the antennas, deflecting panels (boards) and target sites (baskets). The main steps of the collapsing bubble dynamics are also schematically shown, from left to right, by the first line of structures: (a) bubble generation by the laser pulses, (b) asymmetry in the collapsing process, (c) final collapse of the bubble, and (d) target site filled by nanoparticles and analytes ready for the tests.
