Abstract
This application discloses ZnO film transistor-based immunosensors (ZnO-bioTFT), 2T biosensor arrays formed from two integrated ZnO-bioTFTs, 1T1R-based nonvolatile memory (NVM) arrays formed from ZnO-bioTFT (T) integrated with ZnO-based resistive switches (R), as well as integrated bioTFT (IBTFT) sensor systems formed from 2T biosensor arrays and 1T1R NVM arrays. Through biofunctionalization, these biosensors can perform immunosensing with high sensitivity and selectivity, and therefore have a wide range of applications, for example, in detecting target biomolecules or small molecules, and potential application in cancer diagnosis and treatment.
