A sandwich-type electrochemical aptasensor for determination of MUC 1 tumor marker based on PSMA-capped PFBT dots platform and high conductive rGO-N′1,N′3-dihydroxymalonimidamide/thionine nanocomposite as a signal tag

In this work, we developed a simple strategy to fabricate a sandwich-type electrochemical aptasensor for determination of ultra-trace MUC 1 using the IL/nafion/PSMA-capped PFBT dots film modified with aptamer as the sensing layer and aptamer/rGO/Th label nanobioconjugate.179
