Clinical sample analysis on DT-LCHA platform. A The electrochemical signal for sEV-miR-1246 profiling of Healthy doners (HD); benign gastric tumor patients (BGT); Stage I-II gastric cancer patients (Stage I-II); Stage III-IV gastric cancer patients (Stage III-IV) (*p < 0.05, **p < 0.01; paired t test). B ROC curve between gastric cancer patients (Stage I-IV, Stage I-II) and healthy donors. C The ROC curve was between gastric cancer patients (Stage I-IV, Stage I-II) and benign gastric tumor patients
