Treating bone defects coupled with pathogen infections poses a formidable challenge to clinical medicine. Thus, there is an urgent need to develop orthopedic implants that provide excellent antibacterial and osteogenic properties. Of the various types, copper-based biomaterials capable of both regenerating bone and fighting infections are an effective therapeutic strategy for bone tissue engineering and therefore have attracted significant research interest. This review examines the advantages of copper-based biomaterials for biological functions and introduces these materials' antibacterial mechanisms. We summarize current knowledge about the application of copper-based biomaterials with antimicrobial and osteogenic properties in the prevention and treatment of bone infection and discuss their potential uses in the field of orthopedics. By examining both broad and in-depth research, this review functions as a practical guide to developing copper-based biomaterials and offers directions for possible future work.

Copper, an essential trace element, is integral to numerous metabolic pathways across biological systems. In recent years, copper-based biomaterials have garnered significant interest due to their superior biocompatibility and multifaceted functionalities, particularly in the treatment of malignancies such as sarcomas and cancers. On the one hand, these copper-based materials serve as efficient carriers for a range of therapeutic agents, including chemotherapeutic drugs, small molecule inhibitors, and antibodies, allowing them for precise delivery and controlled release triggered by specific modifications and stimuli.

Copper-based nanoparticles have garnered significant interest in cancer therapy due to their ability to induce oxidative stress and cuproptosis in cancer cells. However, their antitumor effectiveness is constrained by the dynamic redox balance and the metabolic shift between oxidative phosphorylation and glycolysis. Here, a polydopamine-coated copper-α-ketoglutaric acid (α-KG) coordination polymer nanoparticle (CKPP) is designed for combined pyroptosis-cuproptosis cancer immunotherapy by amplifying reactive oxygen species (ROS) production and regulating cellular metabolism.

Abnormal tumor metabolism leads to tumor growth, metastasis, and recurrence, reprogramming tumor metabolism and activating potent anti-tumor immune response have been demonstrated to have good therapeutic effects on tumor elimination. Copper-based nanomaterials involved in cuproptosis show great prospects in these two aspects, but their efficiency is restricted by Cu homeostasis and the toxicity of the chelator. Here, the pH-responsive AuNRs@CuO core-shell plasmonic hybrid nanorods (ACNRs) have been successfully fabricated to realize microenvironment-controlled release at the tumor site for the combined therapy of cuproptosis and photothermal treatment.

The rise of antimicrobial resistance necessitates innovative strategies to combat persistent infections. Metal-organic frameworks (MOFs) have attracted significant attention as antibiotic carriers due to their high drug loading capacity and structural adaptability. In particular, 2D MOF nanosheets are emerging as a notable alternative to their traditional 3D relatives due to their remarkable advantages in enhanced surface area, flexibility and exposed active region properties.
