Abstract

Real-time, remote monitoring of human biomarkers is essential for personalized medical diagnostics. Hydrogen sulfide (H2S), a key endogenous gas, serves as a crucial biomarker for conditions such as oral diseases. However, accurately detecting ppb-level H2S in high-humidity environments remains a challenge. Herein, we develop a Pt-loaded CrVN2 fuel cell-type H2S sensor that exhibits high humidity resistance, ultralow detection limits (50 ppb), rapid response (4 s), and exceptional selectivity. The stable electronic structure of CrVN2 ensures a consistent response across a wide relative humidity range (9%-79%). Furthermore, a wireless detection system incorporating the Pt/CrVN2 sensor was designed and validated for breath diagnosis, demonstrating its practical application in smart healthcare. This study highlights the potential of Pt/CrVN2 sensor as a promising platform for real-time, sensitive biomarker detection, contributing to the advancement of next-generation medical diagnostics.

用于H2S生物标志物检测的耐湿Pt/CrVN2燃料电池传感器。

实时、远程监测人体生物标志物对于个性化医疗诊断至关重要。硫化氢（H2S）是一种关键的内源性气体，是口腔疾病等疾病的重要生物标志物。然而，在高湿环境中准确检测ppb级H2S仍然是一个挑战。在此，我们开发了一种pt负载的CrVN2燃料电池型H2S传感器，具有高抗湿性、超低检测限（50 ppb）、快速响应（4 s）和卓越的选择性。CrVN2稳定的电子结构确保在较宽的相对湿度范围内（9%-79%）具有一致的响应。此外，设计并验证了一种结合Pt/CrVN2传感器的无线检测系统，用于呼吸诊断，展示了其在智能医疗中的实际应用。这项研究强调了Pt/CrVN2传感器作为实时、灵敏的生物标志物检测平台的潜力，有助于推进下一代医学诊断。
