Abstract

We have developed a novel molecular logic gate system based on the incorporation of aptamer-crosslinked hydrogels. Modified gold nanoparticles are used as the output signal, which is visible to the naked eye. This system is designed for AND and OR operations using two chemicals as stimulus inputs.
