Main Methods:

• Literature review focusing on gas-releasing nanomaterials for wound healing.
• Analysis of chemical design principles for spatiotemporal control of gas release.
• Evaluation of bactericidal activity and mechanisms of gases like NO, CO, H2S, O2, CO2, and H2.
• Exploration of synergistic therapeutic approaches.

Main Results:

• Gas-releasing nanomaterials demonstrate effective broad-spectrum antibacterial activity without inducing resistance.
• Specific gases (NO, CO, H2S, O2, CO2, H2) possess unique properties beneficial for wound healing.
• Spatiotemporal control over gas release enhances therapeutic precision and efficacy.
• Synergistic combinations of gases show potential for improved wound repair.

Conclusions:
