Figure Legend Snippet: Top panels: Detection probability curves obtained experimentally for a specific nanoparticle sample/irradiation regime, at varying concentrations. Circles indicate experimental measurements and lines, fitting curves based on and . The examined concentrations in each figure (shown in 10 9 ml −1 ) correspond to the ones indicated in the figures on the bottom panel. As the concentration becomes smaller, the fluence that corresponds to a 50% detection probability increases. Bottom panels: Detection probability as a function of particle concentration is plotted for the experimental data, which demonstrates a good agreement with the proposed model of (shown with solid black lines).
Techniques Used: Irradiation, Concentration Assay
Figure Legend Snippet: (a) Size-dependent, experimentally evaluated fluence thresholds of detectable cavitation bubbles of spherical AuNPs (left) and the ones of AuNS (right) for all applied laser pulse widths. (b) Results of double 55 fs pulse experiments as a function of pulse delay. All fluence thresholds have been normalized to the one acquired under single 55 fs pulse excitation.

Figure Legend Snippet: (a) Calculated ratio of the energy deposited in the plasma ( E p ) and in the nanoparticle ( E NP ) at the experimental threshold fluencies. (b) Diagram of the ratio versus pulse width. The solid black curves correspond to the crossover pulse width t p,t , which marks the transition from plasma-mediated to photothermal cavitation for various nanoparticle sizes (shown in [nm]). The curves were calculated based on and numerical analysis shown in Section S3 of the ESI. The ratios E p / E NP for the cases of AuNS, 200 nm, 150 nm, and 100 nm particles, as shown in (a), are included for comparison. For the cases of 80 nm, 60 nm, and 40 nm particles, becomes smaller and all their corresponding values reside within the plasma-mediated region, below the transition curve (not shown in the diagram).
