Ana bincikar nanoparticles don aikace-aikace iri-iri saboda keɓantattun kayan aikinsu na zahiri. Misali, ana amfani da nanoparticles na azurfa a cikin samfuran kasuwanci don abubuwan kashe ƙwayoyin cuta da na fungal. Wasu daga cikin waɗannan samfuran na iya haifar da nanoparticles na azurfa isa ga yanayin ruwa. Don haka, nanoparticles suna haifar da damuwa ga lafiyar ɗan adam da nau'ikan ruwa. Mun yi amfani da layin salula na medaka (Oryzias latipes) don bincika cytotoxicity da genotoxicity na 30 nm diamita na azurfa nanospheres. Jiyya na 0.05, 0.3, 0.5, 3 da 5 μg/cm2 sun haifar da 80, 45.7, 24.3, 1 da 0.1% na rayuwa, bi da bi, a cikin tsarin mulkin mallaka. Nanoparticles na azurfa kuma sun haifar da ɓarna na chromosomal da aneuploidy. Jiyya na 0, 0.05, 0.1 da 0.3 μg/cm2 sun haifar da lalacewa a cikin 8, 10.8, 16 da 15.8% na metaphases da 10.8, 15.6, 24 da 24 duka aberrations a cikin metaphases 100, bi da bi. Wadannan bayanai sun nuna cewa nanoparticles na azurfa sune cytotoxic da genotoxic zuwa ƙwayoyin kifi.
