The study developed a novel method for preparing HA/HLC bio-composite membranes, which demonstrated enhanced biological activity and superior therapeutic performance through surface modification-assembly process.
The merits of hyaluronic acid (HA) as a representative biological carbohydrate polymers especially in bioactivity and tailorability makes it ideal building block for the engineering of tissue engineering scaffolds. HA-based biocomposites integrate the characteristics of multi-component materials, possessing versatility and further improving the therapeutic efficacy. Human like collagen (HLC), which is hydrophilic, biomimetic, and bio-safe, with human tissue-derived collagen biofunction, has attracted extensive attention worldwide. Herein, we developed a novel method for HA/HLC bio-composite membranes preparation, comprising one-step surface modification-assembly process by which the HLC self-assembles are simultaneously loaded on the oxidizedmodified HA (oxi-HA) from the surface/interface micro-scale. Comprehensive material characterizations and in vitro/in vivo biostudies proved that the HLC/oxi-HA composite membranes exhibited significantly enhanced biological activity, hemostatic performances, and wound healing properties compared to that of the pristine HA. The results of this study highlight the great potential of the prepared biomimetic HLC/oxi-HA bio-composites as a new generation of multifunctional HA-based wound-healing materials.
