Tumor Detection: Remarkable NIR Enhancement of Multifunctional Nanoprobes for In Vivo Trimodal Bioimaging and Upconversion Optical/T2‐Weighted MRI‐Guided Small Tumor Diagnosis (Adv. Funct. Mater. 46/2015)

On page 7119, S. J. Zeng, J. H. Hao, and co-workers present a multifunctional upconversion nanoprobe with remarkable enhancement of near-infrared emission for trimodal bioimaging, combining upconversion optical, T2-weighted magnetic resonance, and computed tomography imaging. Importantly, these nanoprobes are successfully used for in vivo diagnosis of small tumors (down to 4 mm) based on upconversion optical and T2-weighted magnetic resonance imaging.
