Microfluidic-engineered Chinese herbal nanocomposite hydrogel microspheres for diabetic wound tissue regeneration.

ABSTRACT: Microfluidic-engineered hydrogel microspheres have emerged as a promising avenue for advancements in tissue engineering and regenerative medicine, particularly through the precise manipulation of fluids to achieve personalized composite biomaterials. In this study, we employed microfluidic technology to fabricate hydrogel microspheres (HMs) using Chinese herbal Bletilla striata polysaccharide (BSP) as the primary material. Concurrently, the natural active ingredient 20(S)-protopanaxadiol (PPD) was encapsulated within the HMs in the form of liposomes (PPD-Lipo), resulting in the formation of nanocomposite hydrogel microspheres (PPD-Lipo@HMs) intended for diabetic wound tissue repair. PPD-Lipo@HMs are characterized by the expansive specific surface area, adjustable mechanical properties, and
