This study presents a highly sensitive and selective method for protein screening using surface-enhanced Raman scattering facilitated by octahedral Au nanotrenches, a novel class of nanoparticles with narrow trench-like excavations in the facets of Au octahedrons. The unique geometry of these nanotrenches maximizes electromagnetic near-field focusing by confining and reflecting light within the trenches, enhancing detection sensitivity. Using Ni ions and molecular linkers for selective binding of His-tagged proteins, the approach achieved 100% sensitivity and selectivity in distinguishing His-tagged human serum albumin from native human serum albumin, demonstrating its exceptional protein screening capabilities.
