Introduction
Gene editing technologies—particularly CRISPR-based systems—have revolutionized genetic engineering by enabling precise modification of DNA. However, successful gene editing depends on numerous parameters, including guide RNA design, delivery efficiency, editing timing, cellular context, and off-target minimization. Optimizing these parameters through traditional trial-and-error approaches is time-consuming, resource-intensive, and often inconsistent.
Artificial Intelligence (AI) provides a powerful solution by enabling data-driven optimization of gene editing processes. When integrated with Lab-on-a-Chip (LOC) platforms, AI algorithms can analyze complex datasets, predict optimal editing conditions, and dynamically refine gene editing workflows in real time.
