DNA?Engineered Hydrogels with Light?Adaptive Plasmonic Responses

Orientational control of anisotropic plasmonic nanoparticles is an attractive proposition to generate dynamic responses. Particularly, the use light as a stimulus modulate orientation extremely useful owing its spatiotemporal operative ability. This work showcases light-mediated approach tune orientational features gold nanorods in DNA-engineered hydrogel materials. The strategy relies on visible-light-induced photothermal effects cause deformation matrix, resulting temperature-controlled polarization-dependent optical responses whose anisotropy are highly adaptive nature DNA crosslinks. visible-light-mediated showcased here can open novel avenues create light-responsive materials with reconfigurable
