Background:

• DNA strand displacement (SD) reactions are fundamental to synthetic nucleic acid systems like molecular circuits and sensors.
• Existing design frameworks address various goals and conditions, but predicting reaction kinetics remains a significant challenge.

Purpose of the Study:

• To focus on the design and analysis of individual SD reactions, rather than network-level architectures.
• To highlight kinetic mechanisms, structural determinants, and the limitations of current predictive modeling for SD reactions.

Main Methods:

• Review of existing literature on DNA strand displacement reaction design and analysis.
• Analysis of kinetic mechanisms and structural factors influencing SD reactions.
• Evaluation of the current state and limitations of predictive modeling in this field.

Main Results:

• Identified key challenges in reliably predicting the kinetics of individual SD reactions.
• Highlighted promising innovations in SD reaction design.
• Analyzed factors hindering predictive accuracy in current models.

Conclusions:

• Future directions are needed to achieve more robust and programmable behavior in DNA-based systems.
• Further research should focus on improving the predictive accuracy of SD reaction kinetics.
• Enhanced understanding of individual SD reaction mechanisms is crucial for advancing synthetic nucleic acid systems.
