What I didn't find covered is how hard is to maintain the "sensing" state of the sensor for more than a single measurement. If I understood correctly, actual antibodies have to be put on the graphene. The described process for that is far from trivial, in the paper: "The fabricated graphene-based device was soaked in 2 mM PBASE (Thermo Fisher Scientific, Waltham, MA) in methanol for 1 h at room temperature and then rinsed several times with PBS and DI water. Finally, the functionalized device was exposed to 250 μg/mL SARS-CoV-2 spike antibody for 4 h."
