What is Microfluidic DEP Printing?
Microfluidic DEP printing is a cutting-edge technique that utilizes electric fields to manipulate cells within microfluidic channels. Unlike traditional methods, DEP printing offers non-invasive and highly precise control over cell positioning, making it ideal for applications like tissue engineering, drug screening, and single-cell analysis. The process relies on the dielectrophoretic force, which acts on cells based on their electrical properties and the applied field frequency.

How Does Microfluidic DEP Printing Work?
The core principle of DEP printing involves applying an alternating electric field across microelectrodes integrated into a microfluidic device. Cells suspended in a fluid medium experience a dielectrophoretic force that either attracts or repels them, depending on their polarizability relative to the medium. This force allows for the precise arrangement of cells into desired patterns or structures.
Key Components of DEP Printing Systems
- Microfluidic Chip: Contains microchannels and electrodes for cell manipulation.
- Electric Field Generator: Provides the alternating current required for DEP forces.
- Cell Suspension: The medium containing cells to be manipulated.
- Imaging System: Monitors cell positioning in real-time.
