Voltammetric immunosensor for E-cadherin promoter DNA methylation using a Fe3O4-citric acid nanocomposite and a screen-printed carbon electrode modified with poly(vinyl alcohol) and reduced graphene oxide
Silencing of tumor suppressor genes (E-cadherin) by promoter DNA methylation may lead to the development of invasive phenotypes in epithelial tissues. The authors describe an electrochemical nanobiosensor for ...
