Accordingly+ACYAIw-44+ADs- molecularly imprinted polymers (MIPs) as artificial antibodies prove to be an ideal preliminary detection platform for specific identification of target templates+ACYAIw-44+ADs- with superior sensitivity and detection limit (DL). MIPs detect the target template with the +ACI-lock and key+ACI- mechanism+ACYAIw-44+ADs- the same as natural monoclonal antibodies+ACYAIw-44+ADs- and present ideal stability at ambient temperature+ACYAIw-44+ADs- which improves their practicality for real applications. Herein+ACYAIw-44+ADs- a 2D MIP platform consisting of decorated graphene oxide with the interconnected complex of polypyrrole-boronic acid is developed that can detect the trace of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen in aquatic biological samples with ultrahigh sensitivity/specificity with DL of 0.326 and 11.32 fg mL-1 using voltammetric and amperometric assays+ACYAIw-44+ADs- respectively. Additionally+ACYAIw-44+ADs- the developed MIP shows remarkable stability+ACYAIw-44+ADs- selectivity+ACYAIw-44+ADs- and accuracy toward detecting the target template+ACYAIw-44+ADs- which paves the way for developing ultraspecific and prompt screening diagnostic configurations capable of detecting the antigen in 1 min or 20 s using voltammetric or amperometric techniques+ADw-BR /+AD4- +ADw-B+AD4-Author keywords:+ADw-/B+AD4- Graphene+ACYAIw-42+ADs- Molecularly imprinted polymers+ACYAIw-42+ADs- Polypyrrole+ACYAIw-42+ADs- SARS-CoV-2+ACYAIw-42+ADs- ultrasensitive detection of viral antigens
