Perovskite nanomaterials are increasingly used in energy storage, catalysis, and sensing, but their effects on human health and the environment remain poorly understood, especially for newer types. This study presents the first direct comparison of two emerging perovskites, nickel-titanate (NiTiO3) and calcium-manganite (CaMnO3) tested simultaneously in human epithelial cells (A549) and Escherichia coli bacteria, providing a dual-host perspective on their biological impact. The materials differed notably in shape and size: NiTiO3 formed smooth, spherical-like particles (~367 nm), while CaMnO3 had irregular, sharp-edged structures (~588 nm). Neither caused destruction of red blood cells up to 400 μg/mL, although CaMnO3 induced visible deformation. This research highlights the distinct toxicity mechanisms attributed to morphology and chemical composition, underscoring the potential environmental and health risks associated with these perovskite nanomaterials. Both perovskites promote OMV-mediated horizontal gene transfer, raising concerns about the spread of antibiotic resistance.
