As cells pass between electrodes, a brief electric pulse temporarily alters the cell membrane and creates pores. These openings permit DNA, RNA, proteins, or other biological cargo to cross into the cell. After the pulse, the membrane reseals, allowing the technique to combine transient permeability with continued cell processing.
Controlled pulses determine when cells experience membrane permeabilization as they move through the fluidic system. Their brief, regulated application supports cargo entry while allowing membrane resealing afterward. This timing is central to processing cells continuously rather than exposing them to an uncontrolled electrical treatment throughout the entire workflow.
The continuous-flow format processes cells as they travel through a fluidic pathway, whereas batch handling treats a collected population as a discrete group. This distinction can reduce reliance on repeated batch operations and support faster, more scalable processing. It also makes the approach compatible with integration into microfluidic platforms.
The method can introduce several classes of biological material, including DNA, RNA, proteins, and other cargo. That range makes it relevant to experiments requiring genetic material, gene-editing components, or protein delivery. The appropriate cargo depends on the intended cell-engineering or biological research objective.
A typical workflow moves cells and their selected cargo through a fluidic system, directs them between electrodes, and applies brief controlled electric pulses during passage. The temporary membrane pores allow entry, after which the membrane reseals as cells continue through the system. This arrangement supports an integrated, continuous processing sequence.
Researchers may choose this format when they need rapid processing, scalable handling, or consistent delivery across large cell populations. It is also useful when the transfection step must connect with a microfluidic workflow. These features make the method relevant to studies and development programs that cannot rely exclusively on discrete batch operations.
In bioengineering, the technique supports gene editing, cell-based therapies, vaccine development, and research requiring delivery of biological materials to many cells. Its continuous format can help connect molecular delivery with larger-scale cell processing. The method therefore serves both exploratory laboratory studies and workflows focused on scalable biological production.
