Published: April 5, 2023

The bone defects caused by trauma are inevitably accompanied soft tissue damage. development of multifunctional bioactive biomaterials with integrated and regeneration is necessary needed urgently in orthopedics. In this work, we found that the photoactivated MXene (Ti3C2Tx) nanosheet showed positive effects on promoting both regeneration. We further investigated detailed effect potential mechanism Photoactivated shows a good thermal robust antibacterial activity to inhibit expression inflammation factors methicillin-resistant Staphylococcus aureus (MRSA) infection induces pro-angiogenic wound repair. can also regulate osteogenic differentiation adipose-derived stem cells (ADSCs) through ERK signaling pathway activating heat shock protein 70 (HSP70) enhancing repair tissue. This work sheds light photothermal activation as an efficient strategy for simultaneously.

Titanium‐Based Nanoarchitectures for Sonodynamic Therapy‐Involved Multimodal Treatments

Small, Journal Year: 2023, Volume and Issue: 19(12)

Published: Jan. 15, 2023

Sonodynamic therapy (SDT) has considerably revolutionized the healthcare sector as a viable noninvasive therapeutic procedure. It employs combination of low-intensity ultrasound and chemical entities, known sonosensitizer, to produce cytotoxic reactive oxygen species (ROS) for cancer antimicrobial therapies. With nanotechnology, several unique nanoplatforms are introduced sonosensitizers, including, titanium-based nanomaterials, thanks their high biocompatibility, catalytic efficiency, customizable physicochemical features. Additionally, developing sonosensitizers facilitates integration SDT with other treatment modalities (for example, chemotherapy, chemodynamic therapy, photodynamic photothermal immunotherapy), hence increasing overall results. This review summarizes most recent developments in tissue engineering using titanium mediated SDT. The synthesis strategies biosafety aspects Titanium-based also discussed. Finally, various challenges prospects its further development potential clinical translation highlighted.

Published: April 15, 2024

Fabrication of composite hydrogels can effectively enhance the mechanical and functional properties conventional hydrogels. While ceramic reinforcement is common in many hard biological tissues, ceramic-reinforced lack a similar natural prototype for bioinspiration. This raises key question: How we still attain bioinspired mechanisms without mimicking specific composition structure? Abstracting hierarchical design principles materials, this study proposes fabrication strategy organo-hydrogels, featuring (1) aligned platelets through direct-ink-write printing, (2) poly(vinyl alcohol) organo-hydrogel matrix reinforced by solution substitution, (3) silane-treated platelet-matrix interfaces. Unit filaments are further printed into selection macro-architectures, leading to high stiffness, strength, toughness (fracture energy up 31.1 kJ/m
