CuO NPs increase the release of lactate dehydrogenase (LDH) production. (A) control untreated cells. (B) Cells treated with 25 µg cells mL⁻¹ of CuO NPs. (C) Cells treated with 50 µg cells mL⁻¹ of CuO NPs. (D) Cells treated with 100 µg cells mL⁻¹ of CuO NPs. 1% Triton-x was employed for positive control reference (E). LDH release was measured at 490 nm. Results are represented as mean ± SD.
