Three-dimensional (3D) printing technology has revolutionized the design and fabrication of bone scaffolds, offering precise customizable solutions for tissue engineering. In this study, we developed polycaprolactone (PCL) scaffolds that incorporated gold plasmonic blackbodies (AuPBs) to harness photothermal properties temperature-controlled regeneration. The AuPB-PCL demonstrated enhanced mechanical strength, a tunable thermal response under near-infrared (NIR) laser irradiation, improved osteogenic potential. Photothermal stimulation effectively modulated cellular responses, promoting osteoblast proliferation, alkaline phosphatase (ALP) activity, mineralization. Notably, mild hyperthermia (39-41 °C) induced by irradiation optimized osteogenesis, while excessive temperatures (≥42.5 impaired function due mitochondrial stress oxidative damage. These findings highlight potential controlled regeneration, promising strategy precise, completely noninvasive repair.
