| Outline of Final Research Achievements |
We have investigated the response of liquids heated by Au nanoparticles with tailored nanomorphology, which are irradiated with a laser of which wavelength is matched with that of plasma resonance. By using our originally developed apparatus, we have succeeded to measure photoacoustic signals from Au nanoparticles irradiated with a pulse laser and have found that they showed the non-linear dependence on fluence of the incident laser.
On the other hand, we have developed a technique to generate microbubbles at our favorite time and locations. In addition, by the local temperature gradient induced by laser irradiation, we have succeeded to generate strong flows around the bubbles.
These techniques are expected to be applied to new engines for microfluids and to focusing/classification of micro- and nanoparticles.
