Abstract

En 中文

• Novel composites with shape morphing, photothermal, and imaging properties were developed. • NIR-assisted shape recovery was established in 3D-printed parts near physiological temperature. • The nanocomposites exhibited multimodal imaging under in vivo fluorescence and photoacoustic modes. • The nanocomposites were printed into stents and scaffolds with tunable shape recovery.
