| Summary: | Hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) detection in both liquid and gas phases has garnered significant attention due to its importance in various biological and industrial processes. Monitoring H<sub>2</sub>O<sub>2</sub> levels is essential for understanding its effects on biology, industry, and the environment. Significant advancements in the physical dimensions and performance of biosensors for H<sub>2</sub>O<sub>2</sub> detection have been made, mainly through the integration of fluorescence techniques and nanotechnology. These advancements have resulted in more sensitive, selective, and versatile detection systems, enhancing our ability to monitor H<sub>2</sub>O<sub>2</sub> in both liquid and gas phases effectively. However, limited comprehensive reviews exist on the detection of vaporized H<sub>2</sub>O<sub>2</sub>, which is used in disinfection and the production of explosive agents, making its detection vital. This review provides an overview of recent progress in nanostructured fluorescence sensors for H<sub>2</sub>O<sub>2</sub> detection, covering both liquid and gas phases. It examines various fluorescence-based detection methods and focuses on emerging nanomaterials for sensor development. Additionally, it discusses the dual applications of H<sub>2</sub>O<sub>2</sub> detection in biomedical and non-biomedical fields, offering insights into the current state of the field and future directions. Finally, the challenges and perspectives for developing novel nanostructured fluorescence sensors are presented to guide future research in this rapidly evolving area. |
