Shedding Light on Plasmonics: Creating Colors Using Gold and DNA with Dr. Manuguri & Dr. Ryssy

In this episode, we have a fascinating discussion with Dr. Manuguri and Dr. Ryssy on the dynamic world of plasmonic nanoparticles and the potentials of light as a modulating agent. They introduce us to their recent work on the orientational control of anisotropic plasmonic nanoparticles—a captivating approach that promises to create dynamic plasmonic responses.The researchers guide us through their cutting-edge work where they used visible-light-induced photothermal effects to manipulate the orientation of gold nanorods within DNA-engineered hydrogel materials. They explain how the light-mediated approach prompts a deformation in the hydrogel matrix, leading to temperature-controlled polarization-dependent optical responses. The anisotropy of these responses proves to be highly adaptable to the nature of DNA crosslinks.We delve into the wider implications of their findings, which could potentially pave the way for novel light-responsive materials with reconfigurable plasmonic responses. Join us as we explore the frontier of nanotechnology and its transformative potential.Keywords: Dr. Manuguri, Dr. Ryssy, Plasmonic Nanoparticles, Light-Mediated Approach, Gold Nanorods, DNA-Engineered Hydrogel Materials, Photothermal Effects, Light-Responsive Materials, Nanotechnology.https://doi.org/10.1002/adfm.202201249 DNA-Engineered Hydrogels with Light-Adaptive Plasmonic Responses Orientational control of anisotropic plasmonic nanoparticles.
