Abstract:
In this work, two DNA nanodevices were constructed utilizing a DNA strand displacement reaction. With the assistance of gold nanoparticles (AuNPs) and gold nanorods (AuNRs), the autonomous reactions can be reflected from the aggregation states of nanoparticles. By sequence design and the two non-overlapping double hump-like UV-vis spectral peaks of AuNPs and AuNRs, two logic gates with multiple inputs and outputs were successfully run with expected outcomes. This method not only shows how to achieve computing with multiple logic calculations but also has great potential for multiple targets detection.
