The synergistic physical and biological effects of selective targeting and activation of plasmonic nanoparticles were studied for a transient vapor nanobubble mode. Simultaneous optical activation of two plasmon resonances in multi- nanoparticle clusters significantly improved the selectivity and efficacy of the nanobubble generation through and was termed “rainbow plasmonic nanobubbles.” The rainbow nanobubble mechanism has been studied in water and in living cells in vitro . This mechanism provided maximal selectivity of the nanobubble generation in both models and therefore, can the therapeutic selectivity and optical contrast of gold nanoparticles in a heterogeneous physiological microenvironment at cell level.
