Fundamental characteristics of ultrasonic green formulations using Avena sativa L. extract-mediated gold nanoparticles and electroconductive nanofibers for cardiovascular nursing care

Abstract

In the pursuit of novel approaches to address chronic heart failure and enhance cardiovascular nursing care, environmentally sustainable nanomaterials have taken center stage. Recent progress in regenerative medicine has opened doors for the use of biocompatible biomaterials that provide mechanical support to damaged heart tissue and facilitate electrical signaling. This study was dedicated to developing advanced electroconductive nanofibers by incorporating eco-friendly Avena sativa L. extract-mediated gold nanoparticles (AuNPs) into polyaniline to create an intricate cardiac patch. The AuNPs were synthesized through an environmentally friendly chemical process aided by ultrasonic conditions. Comprehensive physicochemical analyses, such as UV–Vis spectroscopy, SEM, TEM, DPPH assay, and XRD, were carried out to characterize the AuNPs. These AuNPs were then blended with a polycaprolactone/gelatin polymeric solution and electrospun to fabricate cardiac patches, which underwent thorough evaluation using various techniques. The resulting cardiac patch demonstrated excellent hemocompatibility, antioxidant properties, and cytocompatibility, offering a promising therapeutic approach for myocardial infarctions and the advancement of cardiovascular nursing care.
