Application of biogenic silver nanoparticle incorporated nanofibers in biomedical science

Abstract

The applications of nanotechnology are expanding into medical science for designing new medical devices related products. These products can deliver targeted therapies to diseases such as cancer and peripheral artery treatment. Therefore, with the goal to treat peripheral artery disease, we integrated biogenic silver nanoparticles (AgNPs) into polyethylene glycol-polycaprolactone (PEG-PCL) nanofibrous (NFs). The AgNPs-NFs mats were successfully fabricated using a blended electrospinning process. AgNPs with average sizes of 35–55 nm were produced and characterized using multiple techniques such as UV–Vis spectroscopy, TEM, SEM and FTIR. Nanofibrous membranes containing 1 %, 2 %, and 3 % AgNPs by weight were developed, showing a reduction in fiber diameter from 473 nm to 179 nm due to the introduction of charged particles. The scaffold’s suitability and drug release profile were critically analyzed, revealing results consistent with optimal biomedical applications. Preliminary studies indicated that AgNPs dose-dependent inhibition of human umbilical vein endothelial cells (HUVECs) may potentially help prevent atherosclerosis. These findings underscore the potential of AgNPs integrated PEG-PCL NFs mats for advanced biomedical applications.
