• , Russia 10.3762/bjnano.17.80 Abstract Gold nanobipyramids and nanorods of comparable dimensions were synthesized to evaluate and contrast their plasmonic, analytical, and photothermal performance. The bipyramids exhibited a markedly higher absorption spectral quality factor than the nanorods. For surface
