CuO@MnAl NSs have been fabricated by co-precipitation and hydrothermal approach.
MnAl layered doubled hydroxide can be used to wrap n-type CuO nanoparticles.
MnAl layered doubled hydroxide serves as p-type semiconductive material.
CuO@MnAl NSs electrode demonstrates excellent electrochemical performance towards the nonenzymatic sensing of H2O2.
Real-time monitoring of H2O2 from blood serum, urine and secreted by live tumorigenic and normal cells.
