Monitoring the Photothermal Reshaping of Individual Plasmonic Nanorods with Coherent Mechanical Oscillations
(2018-12-03)
Light absorption in gold nanoparticles leads to metal heating that induces photothermal reshaping because of atomic surface diffusion at temperatures well below the gold melting point. In this work, we perform time-resolved ...
High resolution imaging using nanoparticle based probes
(2018)
New plasmonic probes, based on silica microspheres decorated with metal
nanoparticles (Figure 1), are built and used to confine and enhance the electric field
in their interaction with the sample, giving ultra-high optical ...
