Nonenzyme Sensor Based on Metal Organic Frameworks /Porphyrin / Multiwalled Carbon Nanotubes for Detection of Glucose

利用钴卟啉(Co-TCPP)的催化性能、多壁碳纳米管(MWCNTs)的良好导电性和金属有机框架(Co-MOFs)的高密度活性位点,通过温和方法制备了新型复合材料Co-TCPP/MWCNTs@Co-MOFs,并用此材料构筑了一种新型葡萄糖非酶传感器.电化学实验结果表明,该传感器对葡萄糖具有良好的响应.

Metal-organic frameworks（ MOFs） are regarded as a new type of electrochemical sensor due to its excellent properties. In this work,Co-TCPP / MWCNTs @ Co-MOFs composite was prepared in a gentle method,which is a manifest of the combination of the biomimetic catalytic feature of Co-TCPP,the excellent conductivity of MWCNTs and the high density of active sites of Co-MOFs. A new glucose nonezyme sensor was also constructed,which was experimentally proved processing significant response to glucose.
