Over the past two decades, the increasing release of NPs into soils, resulting from production, consumption and waste disposal, has raised significant environmental concerns. Current research focuses on understanding NPs interactions with plants to enable sustainable agriculture. Therefore, the present study examines how CdS NPs affect spinach growth and whether silicon dioxide (SiO\n                          <jats:sub>2<\/jats:sub>\n                          ) NPs can alleviate CdS NPs induced stress.\n                        <\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>\n                          Three\u2010week\u2010old spinach plants were treated for 4\u2009weeks with either 1\u2009mg\/l CdS NPs alone or in co\u2010exposure with three concentrations (1, 20 and 100\u2009mg\/l) of SiO\n                          <jats:sub>2<\/jats:sub>\n                          NPs.

TEM imaging confirmed reduced cellular internalization of CdS NPs. The treatment also induced a strong antioxidant response and increased chlorophyll content by up to 170.10%. Metabolomic analysis revealed significant alterations in metabolites (53\u201375%), primarily affecting pathways related to amino acids, carbohydrates, oxidative phosphorylation and sulphur metabolism.\n                        <\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>\n                          SiO\n                          <jats:sub>2<\/jats:sub>\n                          NPs effectively detoxify CdS NPs in spinach through a dual mechanism: limiting cellular uptake and biochemically triggering a robust antioxidant and metabolic defence system.
