Comparatively, copper microparticles are relatively stable in the system and practically non-toxic, which indicates the importance of toxic estimation of materials at nanoscale. In addition, Cu(ⅱ) ion can induce protein damage, membrane damage, and slight DNA damage at only relatively high concentration.

相比之下，微米铜颗粒相对稳定，几乎无毒，这表明评估纳米材料的毒性具有重要的意义；Cu（II）只有在相对高浓度时才可诱导蛋白质损伤、细胞膜损伤和轻微的DNA损伤。
