The in vitro expansion and activation of T cells utilizing synthetic nanosized artificial antigen presenting cells (aAPCs) have emerged as a promising technique for cancer treatment. Although diverse nanomaterials have been explored as aAPC scaffolds, protein-only nanoparticles have been largely overlooked, despite their high designability and biocompatibility. [...]

Plasmonic lattice nanostructures are of technological interest because of their capacity to manipulate light below the diffraction limit. Here, we present a detailed study of dark and bright modes in the visible and near-infrared energy regime of an inverted plasmonic honeycomb lattice by a combination of Au + focused ion beam lithography with nanometric resolution, optical and electron spectroscopy, and finite-difference time-domain simulations.
