Organ-on-a-chip stands as a pivotal platform for skeletal muscle research while constructing 3D skeletal muscle tissues that possess both macroscopic and microscopic structures remains a considerable challenge. This study draws inspiration from LEGO-like assembly, employing a modular approach to construct muscle tissue that integrates biomimetic macroscopic and microscopic structures. Modular LEGO-like hybrid nanofibrous scaffold bricks were fabricated by the combination of 3D printing and electrospinning techniques. Skeletal muscle cells cultured on these modular scaffold bricks exhibited a highly orientated nanofibrous structure. A variety of construction of skeletal muscle tissues further enabled development by various assembling processes. Moreover, skeletal muscle-on-a-chip (SMoC)…

The residual of malignant tumor cells and lack of bone‐tissue integration are the two critical concerns of bone‐tumor recurrence and surgical failure. In this work, the rational integration of 2D Ti3C2 MXene is reported with 3D‐printing bioactive glass (BG) scaffolds for achieving concurrent bone‐tumor killing by photonic hyperthermia and bone‐tissue regeneration by bioactive scaffolds. The designed composite scaffolds take the unique feature of high photothermal conversion of integrated 2D Ti3C2 MXene for inducing bone‐tumor ablation by near infrared‐triggered photothermal hyperthermia, which has achieved the complete tumor eradication on in vivo bone‐tumor xenografts. Importantly, the rational integration of 2D Ti3C2 MXene…
