Copper-Based Nanozymes: Potential Therapies for Infectious Wounds

Area of Science:

• Biomaterials Science
• Nanotechnology
• Wound Healing Research

Background:

• Bacterial infections impede acute and chronic wound healing, with traditional antibiotics facing challenges like resistance and side effects.
• Nanozymes, nanomaterials with enzyme-like activity, are emerging as potent antimicrobial agents due to their stability, scalability, and multifunctionality.
• Metal-based nanozymes, particularly copper-based nanozymes (CuNZs), show significant promise for wound care due to their broad-spectrum antimicrobial activity and catalytic properties.

Purpose of the Study:

• To review the dual functions of copper-based nanozymes (CuNZs) in combating wound infections and promoting tissue repair.
• To critically evaluate recent advancements in the design and synthesis of CuNZs for wound healing applications.
• To assess the antimicrobial efficacy, healing promotion capabilities, and biosafety of CuNZs in vitro and in vivo.

Main Methods:

• Literature review focusing on studies involving copper-based nanozymes (CuNZs) for wound healing.
• Analysis of research on the synthesis and characterization of various CuNZ formulations.
• Evaluation of in vitro and in vivo data assessing antimicrobial activity, inflammatory response, and tissue regeneration.

Main Results:

• CuNZs demonstrate strong antimicrobial effects against a broad spectrum of bacteria, reducing infection burden in wounds.
• CuNZs exhibit anti-inflammatory properties and actively promote tissue regeneration, accelerating the wound healing process.
• Recent advancements highlight the potential of tailored CuNZ designs for enhanced therapeutic outcomes and safety.

Conclusions:

• Copper-based nanozymes (CuNZs) present a dual therapeutic approach, effectively managing infections while facilitating wound repair.
• CuNZs offer a viable alternative to conventional antibiotics, overcoming limitations such as resistance and side effects.
