Abstract:
By a combination of quantum dot-labelled aptamers and graphene oxide, a hybrid molecular system was developed for the integration of multiple logic gates to implement half adder and half subtractor functions. On the merits of quantum dots, repetitious arithmetic operations and a reliable fluorescent switch were demonstrated.
