High-order 3D nanotube arrays (NTAs) arranged from mesoporous 2D N, B, P co-doped carbon network (NBP-CNW) were synthesize by a facile, well-controllable, eco-friendly and sustainable strategy using task-specific ionic liquids as precursors. NBP-CNW-NTAs modified flexible microelectrode was embed in microfluidic electrochemical biosensor chip for real-time tracking H2O2 secreted from different cancer cells (i.e., breast cancer cells, hepatoma cells and cervical cancer cells) with or without radiotherapy treatment. Furthermore, the functional microelectrode has been integrated into an implantable probe for in situ minimally invasive detection of surgically resected human breast specimens to identify the tumor tissues from the normal one.
