As demonstrated by the results presented in Fig. , the anti-CRP-immobilized SCM-GFETs specifically detected CRP. To assess sensitivity, we conducted measurements on multiple anti-CRP-immobilized SCM-GFETs, as shown in Fig. . Multiple anti-NP-immobilized SCM-GFETs were measured for comparison. The results are plotted in Fig. (a) and (b). The plot in Fig. was fitted using Eq. 2, based on the Langmuir binding model.
