The Emergence of Enzymatic DNA Synthesis (EDS)
As of early 2026, the industry is undergoing a "structural pivot" from traditional phosphoramidite chemistry to Enzymatic DNA Synthesis (EDS).
Traditional methods rely on toxic solvents and are limited in their ability to produce long, complex sequences without errors. EDS, however, utilizes engineered enzymes like Terminal Deoxynucleotidyl Transferase (TdT) to build DNA in a water-based (aqueous) environment.
This transition is not merely an environmental choice; it is a clinical one. EDS allows for the synthesis of "difficult" DNA—sequences with high GC content, repetitive regions, or complex secondary structures—that frequently stall chemical synthesizers. In 2026, this capability is essential for the rapid production of long, double-stranded DNA constructs required for modern gene therapies and synthetic biology projects.
