Resumen:
Plasmon excitation of spherical gold nanoparticles carrying a fluorescentlabeled 30 bp dsDNA cargo, with one chain covalently attached through two S−Aubonds to the surface, results in release of the complementary strand as ssDNA that canbe examined in situ using high-resolution fluorescence microscopy. The release isdependent on the total energy delivered, but not the rate of delivery, an importantproperty for plasmonic applications in medicine, sensors, and plasmon-induced PCR.
