MXene基复合材料在电化学生物传感器检测癌症标志物中的应用进展OA北大核心CSTPCD

The detection of cancer markers is of great significance for the early diagnosis and subsequent treatment of cancer.However,the existing traditional detection methods have some limitations,especially in the early stages of cancer,thus is often difficult to detect in a timely and accurate manner.As an efficient detection technique,electrochemical sensors can meet the requirement of accurate detection of various cancer markers,provide strong support for early diagnosis of cancer,and have broad application prospects.MXene is a new two-dimensional material,which is widely used in electrochemical sensors because of its unique properties such as high electron transfer ability,high conductivity,large specific surface area,good biocompatibility and hydrophilicity and abundant surface chemical groups,etc.This paper reviewed the applications of electrochemical biosensors based on MXene composites in cancer marker detection in recent years,introduced the function of MXene in electrochemical biosensor,and discussed challenges and future development trends of MXene in the early diagnosis of cancer,aiming to provide reference for early detection of cancer.
