过氧化氢(H2O2)既是一种重要的化工产品,又是生物体内众多酶促反应的产物,其在疾病诊断、生物成像、人类反恐等方面有广泛应用.因此,开发灵敏、快速、可靠检测H2O2的方法显得尤为重要.在众多检测手段中,电化学传感具有检测灵敏度高、响应时间短,易于现场、在线检测等优势.目前,H2O2电化学传感器主要包括基于酶的生物传感器和基于纳米材料的无酶传感器2大类.虽然生物酶传感器
Hydrogen peroxide (H 2 O 2) is not only an important chemical product, but also a product of many enzymatic reactions in the organism. It is widely used in disease diagnosis, biological imaging, human anti-terrorism, etc. Therefore, developing sensitive, rapid and reliable detection H2O2 method is particularly important.In many detection methods, electrochemical sensing with high detection sensitivity, short response time, easy on-site, on-line detection and other advantages.Currently, H2O2 electrochemical sensors include enzyme-based biosensors and nano-based There are two major categories of materials for enzyme-free sensors. Although biological enzyme sensors
