Background:

Digital microfluidic biochip (DMFB) technology is advancing, necessitating efficient chip design.
Current module-based designs suffer from resource wastage due to underutilized electrodes and guard cells.
Existing routing-based methods focus on synthesis time and electrode utilization but neglect chip reliability.

Purpose of the Study:

To propose a routing-based synthesis method for DMFBs that incorporates chip reliability.
To address the limitations of existing DMFB design methods by considering reliability as a critical factor.
To improve overall chip utilization and assay efficiency.

Main Methods:

Development of a routing-based synthesis method for DMFBs.
Integration of a Bayesian decision-making (BBD) approach to account for chip reliability during design.
Simulation experiments to evaluate the proposed method's performance.

Main Results:

The proposed BBD method effectively addresses reliability issues in routing-based DMFBs.
The algorithm demonstrates excellent efficiency and convergence performance.
Achieves shorter average assay completion times compared to moduleless synthesis (MLS) and modified-MLS (MMLS) methods.
Exhibits superior electrode usage rates compared to module-based, improved Dijkstra, and improved particle swarm optimization (ID-IPSO) methods.

Conclusions:

The BBD-based design method offers a significant advancement in creating reliable and efficient DMFBs.
This approach provides a more comprehensive design strategy by integrating reliability considerations.
The method proves effective in improving key performance metrics for digital microfluidic biochips.
