Characterization of polyvinyl alcohol and vitex negundo blended bio nanofilm for wound healing scaffold

Abstract

Polyvinyl alcohol blended nanofilms have shown great promise as a material for wound healing applications because of their biocompatibility, biodegradability, and antibacterial characteristics. This article has typically utilized electrospinning to create a scaffold for wound healing meanwhile investigating the characteristics of the polyvinyl alcohol (PVA) and vitex negundo (VN) blend nanofilm. The PVA concentrations were kept at 10% Weight/Volume (W/V), which was then mixed with VN solution at various volumetric ratios and electrospun into nanofilms. Field Emission Scanning Electron Microscopy (FESEM) was used to determine and analyze the nanofiber diameter. The plant extract concentration and the viscosity of the electrospinning solution influenced the fiber diameter to grow from 120.32 nanometers (nm) to 171.11 nanometers (nm). Fourier Transform Infrared Spectroscopy (FTIR) verifies the interaction between plant extract and PVA and records a new peak between 1731 and 1750 cm⁻¹, which represents the production of the ester group. The swellability of the developed sample was studied which is negligibly reduced when the plant extract was added. In comparison to both Gram-positive and Gram-negative bacteria, the pure plant extract and composite nanofibrous web demonstrated greater antibacterial activity. PVA-blended nanofilms can promote cell migration, proliferation, and differentiation, hence promoting wound healing by creating a moist environment.
