BEHAVIOUR OF PLASMONIC NANOPARTICLE-GENERATED CAVITATION BUBBLES
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2013, Vol 58, Issue 3
Abstract
The transient dynamics of cavitation nanobubbles generated through the irradiation of gold nanoparticles, via the particle's plasmonic resonance, very close to the threshold laser fluence for bubble formation, is investigated numerically. Both for short and long laser pulses, the maximum bubble radius is in the nanometer range. The maximum bubble radius is almost proportional to the square root of the laser fluence. For long laser pulses, and very close to the threshold fluence for bubble formation, the energy dependence of the bubble size is stronger. The oscillation time of cavitation nanobubbles is smaller than that predicted by the Rayleigh formula. Excellent agreement was found between previous experimental results and the present calculations. The results indicate that the mechanical effects associated with bubble formation are compatible with intracellular nanosurgery and are also of interest for a gentle transfection of genes into biological cells.
