چکیده	A dual recognition biosensor was developed via introducing aptamer strings and molecular imprinting polymer (MIP) for the selective detection of intact SARS-CoV-2 virus based on screen printed carbon electrode (SPCE) modifed with nickelbenzene tricarboxylic acid-metal–organic framework (Ni3(BTC)2 MOF) synthesized by in situ growth method, SARSCoV-2 S protein-specifc amino-aptamer and electropolymerization of dopamine (ePDA). The proposed biosensor showed an excellent linear relationship between charge transfer resistance (Rct) and increase in virus concentration in the range 10 to 108 plaque-forming units/mL (PFU/mL) with a low detection limit of 3.3±0.04 PFU/mL and response time of 20 min. Compared with single-element sensors (aptamer or MIP), it showed higher selectivity for the SARS-CoV-2 virus and facilitated detection in real samples
