Article Synopsis
- Nanofiber membranes are promising materials for biomedical use due to their beneficial properties like high surface-to-volume ratios and permeability, resembling natural extracellular structures.
- A new thermal bonding method is introduced to securely attach these membranes to thermoplastic polymer platforms without compromising their structure, using localized preheating.
- This technique has been validated through experiments showing stable bonding for up to 3 weeks, enabling its use in various biomedical applications such as building intestinal barrier models and adapting to different material combinations and shapes.
Although direct electrospinning has been frequently utilized to develop a nanofiber membrane-integrated microfluidic chip, the dielectric substrate material retards the deposition of electrospun nanofibers on the substrate, and the rough surface formed by deposited nanofibers hinders the successful sealing. In this study we introduce a facile fabrication process of an electrospun nanofiber membrane-integrated polydimethylsiloxane (PDMS) microfluidic chip, called a NFM-PDMS chip, by applying the functional layer. The functional layer consists of a silver nanowires (AgNWs)-embedded uncured PDMS adhesive layer (SNUP), which not only effectively concentrates the electric field toward the PDMS substrate, but also provides a smooth surface for robust sealing.
