Abstract
Polyepicatechin (PEC) in a hydrogel has previously shown promise in enhancing physiological properties and scaffold preparation. However, it remains unclear whether PEC-based fibers can be applied in skin tissue engineering (STE). This study aimed to synthesize and characterize electrospun PEC physical gels and polylactic acid (PLA) scaffolds (PLAloadedPECsub) for potential use as constructs with human dermal fibroblasts (HDFs). PEC was produced through enzymatic polymerization, as confirmed by Fourier transform infrared (FTIR) spectroscopy. Scanning electron microscopy (SEM) demonstrated the feasibility of producing PLAloadedPECsub by electrospinning. The metabolic activity and viability of HDFs cocultured with the scaffolds indicate that PLAloadedPECsub is promising for the use of STE.

Abstract
Bioinspired and biosafety antioxidant nanoparticle assemblies from natural occurring molecules have been regarded as a class of effective therapeutic nanomaterials for addressing current inflammatory diseases such as acute kidney injury. In this study, a series of epicatechin-assembled nanoparticles have been developed via one-pot enzymatic polymerization of epicatechin. The prepared poly (epicatechin) (PEC) nanoparticles (NPs) showed excellent antioxidant capacity to scavenge multiple toxic free radicals, thus being able to effectively protect cells under oxidative stress conditions in vitro. Furthermore, in the renal ischemia/reperfusion model, blood renal function testing and renal tissue staining revealed a prominent therapeutic effect of PEC NPs. All these findings suggested that this class of bioinspired antioxidant nanoparticles provided a new therapeutic strategy for human ischemia/reperfusion-related diseases.
