Morphological, thermal, and blood-compatible properties of electrospun nanocomposites for tissue engineering application

Abstract

In this work, the morphological, thermal, and blood compatibility properties of prepared polyurethane (PU) and gandharvahasthadi eranda thailam (GHT) nanocomposites were investigated. Morphological and thermal characterization revealed reduced diameter, improved surface roughness, and higher thermal degradation compared to control. The activated partial thromboplastin time (APTT) and prothrombin time (PT) assay revealed that the fabricated nanocomposites displayed delayed blood clotting time owing to improved surface morphology. The hemolytic assay suggested that nanocomposites would be nonhemolytic material due to low hemolytic index of about 1.15% compared to pure PU (2.733%) portraying its safety with the red blood cells. Thus, the newly developed PU/GHT composite scaffold possessing better physicochemical and blood compatibility may be considered as a potential substitute scaffold for replacing damaged tissue. POLYM.
