Simple, modular platforms for detecting biologically relevant proteins are critical for applications in clinical diagnostics, healthcare, and research. Here, we have combined aptamer-based protein recognition with our conformationally-responsive DNA nanoswitches to enable simple, sensitive and specific protein detection. We demonstrate dual detection of two clinically relevant blood proteins, thrombin and VEGF as initial proof of concept.
