Abstract
Herpes simplex virus (HSV) plagues billions of humans with infections globally. We have developed and demonstrated rose-thorn-inspired antiviral fibrous arrays by electrospinning a composite of polycaprolactone (PCL) polymer with a dispersion of anisotropic zinc oxide tetrapod nanoparticles (ZOTeN). This rose-thorn-mimicking material enables physical and chemical protection. Under blue-light stimulation, ZOTeN photocatalyzes the production of hydrogen peroxide for an accessible disinfection and sterilizing mechanism to prolong materials usage. Using scanning electron microscopy and X-ray photoelectron spectroscopy, we confirm the rose-thorn-inspired morphology and the chemical composition, respectively. The fibrous material has dose-dependent antiviral properties against both HSV-1 and HSV-2. The engineered mats can potentially be used for manufacturing antiviral garments, face coverings, and bandages.
