Electrospining Machine: Application and Innovation of Near-Field Direct Writing Technology in Microfluidic Chip Fabrication

Application of Near-Field Direct Writing Technology

This study has achieved precise construction of microchannels in microfluidic chips through the use of near-field direct writing technology. Characterized by its low cost, high precision, and simple process, this technology offers a highly promising direction for the manufacturing of microfluidic chips. Particularly, by optimizing process parameters such as direct writing temperature, inter-electrode voltage, and substrate movement speed, this research effectively controlled the morphology of Electrospun Nanofbers, thereby enhancing the precision and quality of microchannels.

Significant Enhancement of Material Performance

The introduction of a photosensitive resin mixed with polycaprolactone (PCL) material in the study not only enhanced the thermal stability of fiber templates but also significantly improved the adhesion to the substrate. The application of this innovative material made the fiber templates more durable and reliable in the subsequent preparation process of microfluidic chips, addressing the technical challenges of template deformation and demolding difficulties in the past.
