Pore-confined synthesis of ultra-small Pt nanozymes on gold nanobipyramids for electrochemical detection of cancer cell-derived H2O2.
Accurate quantification of H2O2 released by tumor cells is important for characterizing cancer-associated oxidative stress, yet conventional biosensors often face an intrinsic trade-off between catalytic activity and structural stability. Herein, we present a rational strategy for real-time electrochemical monitoring o...
