FIELD EFFECT TRANSISTOR BASED ON TWO-
In at least one illustrative embodiment, a field effect transistor biosensor for detecting pathogens includes a substrate and a channel formed from a two-dimensional single-layer or multi-layer metal chalcogenide (104) functionalized with a biometric element. The biorecognition element may be an antibody, such as an antibody against SARS-CoV-2 spike protein. A method for manufacturing a biosensor includes depositing an amorphous two-dimensional material on a substrate with pulsed laser ablation, crystallizing the amorphous two-dimensional material to generate a two-dimensional monolayer coupled to the substrate, and activating a surface of the two-dimensional material with a biometric element after crystallizing the amorphous two-dimensional material. The composition of the two-dimensional material may be tuned. The substrate may be photolithographically patterned. Other embodiments are described and claimed..
