Artificial receptor‐based protein assays have various attractive features such as a long‐term stability, a low‐cost production process, and the ease of tuning the target specificity. However, such protein sensors are still immature compared with conventional immunoassays. To enhance the application potential of synthetic sensing materials, organic field‐effect transistors (OFETs) are some of the suitable platforms for protein assays because of their solution processability, durability, and compact integration. Importantly, OFETs enable the electrical readout of the protein recognition phenomena of artificial receptors on sensing electrodes. Thus, we believe that OFETs functionalized with artificial protein receptors will be a powerful tool for the on‐site analyses of target proteins. In this Minireview, we summarize the recent progress of the OFET‐based protein assays including the rational design strategies for devices and sensing materials.
