Gold Nanobipyramds as Multiplexed OCT Contrast Agents


The image shows two types of gold nanobipyramids with different aspect ratios, which upon intratumor and subcutaneous injections, display distinct spectral contrast signals in the peritumoral lymphatic vessels in the optical coherence tomography image.
