Zinc Oxide (ZnO) is a useful compound used extensively in rubber, plastics, paints, ceramics, foods, and most notably, in first aid supplies and ointments owing to its anti-bacterial properties. When incorporated into electrospun polycaprolactone (PCL) fibers, it can aid the healing process and prevent infection of the healing wound. Based on a modification of a previously reported method for producing ZnO nanoparticles (NPs) from aqueous solutions of ammoniated ZnCl<sub>2</sub> and sulfuric acid, we have examined in the impact of increasing quantities of polyethyleneglycol (PEG) capping agent on crystallite size as well as nanoparticle aggregate size in aqueous and ethylene glycol solvents using powder X-ray diffraction (PXRD) and dynamic light scattering (DLS), respectively. We have also examined the effect of post-synthetic heat treatment on these parameters as well as the efficacy of incorporation within electrospun PCL fibers. While consistently determining nanocrystallite dimensions of 30-40 nm by PXRD, we found some variability in aggregate sizes determined by DLS.<br/>
