Abstract

Current strategies for high-performance immunoassay generally require a sandwich structure for signal amplification. This strategy is limited to multivalent antigens and complicates the detection scheme. Herein we demonstrate a class of simple one-step ultrasensitive immunoassay with the adoption of double-stranded DNA (dsDNA) as
