Large‐Scale Synthesis of Bi2S3 Nanodots as a Contrast Agent for In Vivo X‐ray Computed Tomography Imaging

A facile strategy for the large-scale fabrication of Bi2S3 nanodots is presented. Surface modification and control over the size of the nanodots is easily achieved. The as-prepared hydrophilic Bi2S3 nanodots exhibit long in vivo circulation time and, more significantly, a contrast efficacy higher than that of the clinical iodinate agent without any adverse effect.
