Bio-inspired NIR responsive Au-pDA@pDA sandwich nanostructures with excellent photo-thermal performance and stability

Recently, bottom-up assembly of plasmonic core-shell nanostructures have attracted the great attention of scientists for effective/efficient photothermal applications. In this study, a novel systematic layer-by-layer strategy was used to fabricate Au-pDA(core)@pDA(shell) sandwich morphologies based on three main steps: 1) the reactive functional groups onto pDA demonstrated zwitterionicity behavior due to the protonation of amino groups at low...
