Reactive oxygen species (ROS) play a significant role in cellular signaling and oxidative stress, with elevated levels often linked to T cell exhaustion various pathological conditions, including cancer. However, the relationship between ROS acute myeloid leukemia (AML) remains unexplored. To address this, we developed high-throughput single-cell platform─T reactive analyzer (TEROSA). The system achieved capture efficiency of up 80% throughput 2400 cells enabled dynamic monitoring triple molecules, intracellular mitochondrial superoxide, on-membrane marker PD-1, secreted extracellular H2O2. Our study evaluated device's performance across multiple lines demonstrated its capability assess production at level. In particular, analyzed from AML patients found significantly increased PD-1 expression compared healthy donors, suggesting potential link AML. These findings highlight utility TEROSA advancing our understanding behavior underscore for broader applications analysis.
