“…From a practical perspective, the possibility to convert light into vapor has been exploited in several scientific areas, including nanoparticle-assisted cancer therapy, − nano- and microfluid manipulation, , and photoacoustic imaging. − Due to the explosive nature of the generated plasmonic nanobubbles, intense acoustic waves are emitted, an effect which may be exploited in the destruction of biological cellular components at the local scale. − …”

When illuminated by a resonant laser, noble metal nanoparticles immersed in liquids can efficiently produce a huge amount of heat and rapidly vaporize surrounding liquid, leading to the nucleation of plasmonic bubbles. Plasmonic bubbles are gaining increasing attention and emerged in numerous applications due to their unique properties and excellent controllability, such as microfabrication, micromanipulation, robot propulsion, molecule enrichment, and clinical therapies. In this review paper, the research progress of plasmonic bubbles in the past decade is summarized, including the plasmonic effect‐induced heat generation, experimental methods of plasmonic bubble observation, growth dynamics of plasmonic bubbles, approaches of optomechanical energy conversion via plasmonic bubbles, as well as their applications. This work provides a comprehensive understanding of the state of the art in the field and inspires researchers to explore more promising applications of plasmonic bubbles in different fields, like biology, microfluidics, and micromanufacturing.

Recently, we demonstrated that the local heating of degassed water can generate water vapor microbubbles and induce a rapid flow around the bubble. Although flow generation involves the self-excited oscillation of bubbles at a local heating point, the conditions under which the bubbles oscillate are not fully understood. In this study, the dependence of microbubble size and oscillation frequency on the concentration of non-condensable gases in water was investigated. A continuous-wave laser beam was focused on a β-FeSi2 thin film, and water was locally heated using the photothermal conversion properties of the film. The results showed that the lower the concentration of non-condensable gases dissolved in water, the smaller the bubble size and the higher the oscillation frequency. Furthermore, it was found that the bubbles oscillate when the amount of non-condensable gas absorbed by the bubbles, i.e., the bubble size, falls below a specific level. This study can provide a new understanding of the bubble oscillation mechanism and lead to the development of fluid control technology using bubbles.
