Enzyme-Free Nucleic Acid Circuits for Fold-Change Detection.

Invited for this month's cover are is the collaborating group of Prof. Hao Pei and Prof. Tong Zhu at East China Normal University, China. The cover picture shows a DNA-only dynamical system and the implementation of a fold-change detection circuit. More information can be found in the Research Article byLikun Wang, Tong Zhu, Hao Pei, and co-workers.
