An MnO2 nanosheet as a label-free nanoplatform for homogeneous biosensing†
Abstract
An ultrathin MnO2 nanosheet is established as a label-free two-dimensional nanoplatform for homogeneous biosensing. Two biosensors based on an MnO2 nanosheet with favourable performances are constructed for OTA and Cat D using different probes and following different sensing principles.
