AbstractNanozymes, nanomaterials with enzyme-like activity, have been considered as promising alternatives of natural enzymes. Molecular logic gates, which can simulate the function of the basic unit of an electronic computer, perform Boolean logic operation in response to chemical, biological, or optical signals. Recently, the combination of nanozymes and logic gates enabled bioinformation processing in a logically controllable way. In the review, recent progress in the construction of nanozyme-based logic gates integrated with their utility in sensing is introduced. Furthermore, the issues and challenges in the construction processes are discussed. It is expected the review will facilitate a comprehensive understanding of nanozyme-based logic systems.

Nonstationary State

Using an intramolecular single-electron transfer process, we show how computing inside a quantum system can be performed using the time evolution driven by the preparation of the system in a nonstationary state. The molecule Hamiltonian is separated in three parts: the input, calculation, and output parts. Two optimization procedures are described in order to design an efficient monoelectronics level structure for molecular logic gates. An XOR gate and a half-adder using six electronic quantum levels are presented in a prospect to integrate a full logic gate inside a single molecule without forcing the molecule to have the shape of an electrical circuit. We foresee the merger of molecular electronics with quantum computation at the nanoscale.

Strand Displacement Reaction

In this paper, I construct an XOR logic gate based on DNA strand displacement reaction, and verify our design through corresponding biochemical experiment. I designed several different DNA strands. Based on two basic DNA strand displacement reaction mechanisms, by adding different input strands and taking the signal of FAM fluorescent group as the output, the XOR logic gate is realized. The result shows that DNA strand displacement technology has important application value in DNA computing, especially in the construction of DNA molecular logic gates.
