Fig. 2From: Recent advances in nanomaterial-driven strategies for diagnosis and therapy of vascular anomaliesCopyright 2022, WileyUS imaging agents shown vascular structure. A The schematic core–shell structure of the PCND. B PCND size distributions are characterized by dynamic light scattering (DLS) method; C TEM of PCNDs. D ALUSA imaging of vasculature and hemodynamics in tumors; up: vascular structures, middle: the distribution of the corresponding blood flow velocity. Down: the distribution of the corresponding blood flow direction. Back to article page
