Abstract
A field effect transistor (FET) with a source electrode and a drain electrode distanced apart from each other on a semi-conductor substrate, and a gate electrode consisting of a uniform layer of reduced graphene oxide encapsulated semiconductor nanoparticles (rGO-NPs), wherein the gate electrode is disposed between and contacts both the source and drain electrodes. Methods of making and assay methods using the FETs are also disclosed, including methods in which the rGO-NPs are functionalized with binding partners for biomarkers.
