- Abstract: BACKGROUND:Photoresponsive nanomaterials offer the combined advantages of nanomaterials and the unique benefits of light responsiveness.They find extensive applications in biomedical fields like tissue regeneration,biological imaging,disease diagnosis,drug delivery,and targeted therapy,making them a research hotspot in the field of functional materials.OBJECTIVE:To summarize the advantages and research progress of photoresponsive nanomaterials in bone tissue regeneration.METHODS:CNKI and PubMed databases were searched using the main English search terms"light-responsive,photoresponsive,nanomaterials,bone defect,bone regeneration,osteogenesis,osseointegration"and main Chinese search terms"light-responsive,nanomaterials,bone defect,bone regeneration,osseointegration."Relevant literature was selected based on inclusion and exclusion criteria,resulting in the inclusion of 59 articles for review.RESULTS AND CONCLUSION:The surface morphology of photoresponsive nanomaterials can promote bone tissue regeneration by directly modulating the gene expression and biological behavior of osteoblasts and indirectly regulating immune-related cells behavior.Photoresponsive nanomaterials can be utilized for photothermal and photodynamic antibacterial purposes to facilitate the repair of infectious bone defects.Mild photothermal stimulation generated by photoresponsive nanomaterials can effectively enhance osteogenesis by upregulating the expression and functionality of osteogenic-related genes and proteins.Photoresponsive nanomaterials can produce electrons under light exposure,thereby achieving non-invasive promotion of bone tissue regeneration by modulating local cellular potential changes.Drug release systems based on photoresponsive nanomaterials can undergo structural changes under specific light sources to promote drug release,providing targeted therapeutic strategies for bone tissue regeneration.
