The major goals of the project were to 1 Construct a photothermal microscope for manipulating nanoparticles through optical forces and measure their optical scattering and absorption spectra as they organize under optical radiation forces. 2 Engineer a coherent array of hundreds of light emitting molecules supported by a symmetric biomolecular template formed of a virus capsid. 3 Determine conditions required for collective relaxation and the nature of light emitted coherence, dynamics, i.e. conditions in which the fluorophores act as an optical antenna array. Identify photonic and molecular structure characteristics, specifically the role of symmetry leading to super-radiance. 4 Assemble the super-radiant virus-like particle around a plasmonic nanoparticle and determine how the chromophore array couple to radiation and localized plasmon modes. 5 Measure collective absorption cross-section using the instrument developed in aim 1, and the samples of aim 2 and 4. Develop collective coupling model based on findings.
