Combining bioinspired nanochannels with ferrocene doped MoS2 nanoplates: Application to ratiometric electrochemical detection of let-7a

Specific Adsorption of Magnetic Fe3O4@hydroxyapatite Nanocomposites to a Hybridized Duplex for Immobilization and Label-Free Electrochemical Biosensing of MicroRNA

“…Numerous pathological studies have shown that the abnormal expression of miRNA let-7a in tumor cells and serum is correlated to many cancers, such as hepatocellular carcinoma (HCC), breast cancer, and pancreatic cancer, making miRNA let-7a one of crucial cancer biomarkers. At present, a variety of methods have been developed to detect miRNA let-7a, such as electrochemiluminescence, , fluorescence assays, and electrochemical methods. , Compared to the other methods, the electrochemical biosensing technology has the advantages of simpleness, low cost, and high sensitivity, which are more conducive to the establishment of practical analytical devices.…”
