铜死亡检测是一种用于评估细胞在高浓度铜离子胁迫下发生死亡的实验方法。高浓度的铜离子可导致氧化应激和细胞损伤，最终导致细胞死亡。检测方法包括荧光探针标记、细胞形态学观察、DNA片段化等。铜死亡检测有助于研究细胞对铜胁迫的应激反应，揭示铜在生物体内的作用机制以及与疾病发生的关系。这项研究对于深入理解金属离子在生物学过程中的作用具有重要意义。

Copper death assay is an experimental method used to evaluate cell death under stress of high concentrations of copper ions. High concentrations of copper ions can cause oxidative stress and cell damage, ultimately leading to cell death. Detection methods include fluorescent probe labeling, cell morphology observation, DNA fragmentation, etc. Copper death detection helps to study the stress response of cells to copper stress and reveals the mechanism of copper's action in organisms and its relationship with disease occurrence. This research is important for a deeper understanding of the role of metal ions in biological processes.
