A) Schematic representation of the design criteria for Rh-6G conjugated DNA aptamer attached gold nano star (GNS) based NSET. Due to the wrapping of ss-DNA on GNS, the NSET occurs between GNA and Rh-6G. B) Scheme shows that spike protein specific ss DNA aptamer binds with COVID-19 antigen, which allows DNA to be unwrapped from GNS. C) Scheme shows that spike protein specific DNA binds with SARS-CoV-2 spike protein pseudotyped baculovirus, which allows ss DNA to be unwrapped from GNS.
