Biomaterial‐Integrated Electroporation for Therapeutic Delivery: From Gene Editing to Tumor Ablation and Immune Modulation

ABSTRACT

Electroporation has evolved from a membrane‐permeabilization method into a versatile therapeutic platform for intracellular delivery, locoregional tumor intervention, and bioelectrically regulated treatment. Depending on pulse intensity and duration, electroporation operates in two distinct modes: reversible electroporation (RE), which transiently permeabilizes the plasma membrane to enable delivery of nucleic acids, proteins, and small molecules while preserving cell viability, and irreversible electroporation (IRE), which causes permanent membrane damage for non‐thermal tissue ablation. Increasingly, the therapeutic scope of electroporation is being expanded through integration with biomaterials, including nanocarriers, hydrogels, soft conductors, and micro/nanoengineered bioelectronic interfaces. These material‐assisted strategies improve cargo protection, field confinement, local retention, tissue conformity, and spatiotemporal control, thereby extending electroporation beyond conventional transfection toward gene editing, engineered cell manufacturing, electrochemotherapy, tumor ablation, immune modulation, and transdermal or localized delivery. In this Review, we summarize the biophysical principles of RE and IRE, discuss how biomaterials reshape electroporation performance across therapeutic settings, compare the design logic of major biomaterial‐assisted electroporation platforms, and highlight key translational challenges, including pulse‐material compatibility, manufacturing scalability, in vivo dosimetry, and regulatory complexity.
