Background:
- Cyclic enzyme systems demonstrate reliable ON-OFF operation, similar to McCulloch-Pitts neuronic equations.
- These systems are applicable for switching circuits in biocomputers.
- A key limitation was the fixed switching time, dependent on input differences.
Purpose of the Study:
- To overcome the input-dependent switching time limitation in cyclic enzyme systems.
- To enable optional control over the switching time of biochemical switching devices.
- To enhance the practical utility of enzyme-based switching circuits.
Main Methods:
- Computer simulations were used to analyze cyclic enzyme system behavior.
- The study introduced pulse perturbation as a novel method.
- The effect of pulse perturbation on switching time was investigated.
Main Results:
- Pulse perturbation allows the switching time to be set independently of input modes.
