Abstract
The abnormal expression of hydrogen peroxide (H2O2) in living cells is closely related to the occurrence and development of tumor diseases. It is a kind potential marker for tumor diagnosis and treatment of tumor diseases. Therefore, it is very meaningful to develop high selective and sensitive method for real-time detecting H2O2 released from cancer cells. Herein, an AgCl cube/porous carbon nanotube composite nanomaterials was successfully fabricated and employed to construct a non-enzymatic electrochemical H2O2 sensor. Test results showed that the proposed sensor displayed the high sensitivity with the detection limit of 5.3 × 10−9 mol/L (S/N = 3). Importantly, it can accurately analyze H2O2 in milk samples and achieve real-time determination of H2O2 secreted from living cancer cells. In addition, the established sensor exhibited good stability and anti-interference ability. This strategy offers a potential way to diagnose tumor diseases.
