Abstract

Exudate management is critical to improve chronic wound healing. Herein, inspired by a Janus-structured lotus leaf with asymmetric wettability, a Janus electrospun short fiber scaffold is fabricated via electrospinning technologies and short fiber modeling. This scaffold is composed of hydrophilic 2D curcumin-loaded electrospun fiber and hydrophobic 3D short fiber via layer-by-layer assembly and electrostatic interactions which can aggregate the wound exudate by pumping from the hydrophobic layer to the hydrophilic via multiple contact points between hydrophilic and hydrophobic fibers, and simultaneously trigger the cascade release of curcumin in the upper 2D electrospun fiber. The 3D short fiber with high porosity and hydrophobicity can quickly aggregate exudate within 30 s after compounding with hydrophilic 2D electrospun fiber via a spontaneous pump. In vitro experiments show that Janus electrospun short fiber has good biocompatibility, and the cascade release of curcumin can significantly promote the proliferation and migration of fibroblasts. In vivo experiments show that it can trigger cascade release of curcumin by aggregating wound exudate, so as to accelerate wound healing process and promote collagen deposition and vascularization. Hence, this unique biometric Janus scaffold provides an alternative for chronic wound healing.
