Erbium-Based Perfusion Contrast Agent for Small-Animal Microvessel Imaging

<div>Dynamic light scattering (DLS) results demonstrating the particle size distribution of a sample of the Er<sub>2</sub>O<sub>3</sub> contrast agent. Average particle size is 72.2 ± 2.2 nm. Results of a suspension that was mixed and subsequently stored for 2 years are shown in S1.</div>
