Abstract
Hydrogels offer attractive matrices for incorporating inorganic metal oxide nanoparticles (NPs) to generate multifunctional hybrid materials, but challenges remain in scalable synthesis and correlating their properties to bio-interaction. Therefore, we report the synthesis and characterization of poly(2-hydroxyethyl methacrylate) (pHEMA) hydrogels, and pHEMA hydrogels encapsulating iron oxide or zinc oxide NPs, using a modified free-radical polymerization. Dose-dependent survivorship studies on Drosophila melanogaster revealed that both NP-embedded hydrogels are tolerated over a wide dose range (e.g., 50–200 mg), although ZnO NP-gels exhibit lower survivorship at some concentrations due to their inherent composition and a wider size distribution of iron oxide NPs.
