The transmission and pathogenesis of highly contagious fatal respiratory viruses are increasing, and the need for an on‐site diagnostic platform has arisen as an issue worldwide. Furthermore, as the spread of respiratory viruses continues, different variants have become the dominant circulating strains. To prevent virus transmission, the development of highly sensitive and accurate on‐site diagnostic assays is urgently needed. Herein, a facile diagnostic device is presented for multi‐detection based on the results of detailed receptor‒ligand dynamics simulations for the screening of various viral strains. The novel bioreceptor‐treated electronics (receptonics) device consists of a multichannel graphene transistor and cell‐entry receptors conjugated to N‐heterocyclic carbene (NHC). An ultrasensitive multi‐detection performance is achieved without the need for sample pretreatment, which will enable rapid diagnosis and prevent the spread of pathogens. This platform can be applied for the diagnosis of variants of concern in clinical respiratory virus samples and primate models. This multi‐screening platform can be used to enhance surveillance and discriminate emerging virus variants before they become a severe threat to public health. A receptor–ligand binding reaction based receptonics platform is presented as a facile diagnostic device to discriminate numerous strains of respiratory viruses. Diagnosis of respiratory viruses and their variants indicate its potential as on‐site screening platform for fatal diseases without the need for complex additional equipment. The newly developed receptonics shows the possibility for the application of clinical samples and samples from primate model.
