With the increasing use of manufactured nanomaterials in consumer products, especially silver nanoparticles (AgNPs), concerns about their environmental impact are rising. Two AgNP formulations were tested, commercial nanosilver product nanArgen™ and a newly eco-designed bifunctionalized (AgNPcitLcys), using marine organisms across three trophic levels, microalgae, microcrustaceans, bivalves. Acute toxicity was assessed on diatom Phaeodactylum tricornutum, brine shrimp larvae Artemia franciscana, bivalve Mytilus galloprovincialis. The behavior media, including stability concentration range (0.001–100 mg/L), also evaluated. Results showed that less stable compared to AgNpcitLcys, releasing more ions exhibiting higher microalgae (100% growth inhibition at 1 mg/L) microcrustaceans (>80% mortality 10 mg/L). Conversely, AgNPcitLcys (10 µg/L) toxic bivalves, possibly due smaller nanoparticle size affecting lysosomal membrane stability. This study highlights how eco-design, such as surface coating, influences toxicity. These findings emphasize importance eco-design minimizing impacts guiding development safer, sustainable nanomaterials.
