AB  - Designing metal sulfides with unique configurations and exploring their 
      electrochemical activities for hydrogen peroxide (H(2)O(2)) and hydrazine 
      (N(2)H(4)) is challenging and desirable for various fields. Herein, hollow 
      microflower-like CuS@C hybrids were successfully assembled and further exploited 
      as a versatile electrochemical sensing platform for H(2)O(2) reduction and 
      N(2)H(4) oxidation, of which the elaborate strategies make the perfect formation 
      of hollow architecture, providing considerable electrocatalytic sites and fast 
      charge transfer rate, while the appropriate introduction polydopamine-derived 
      carbon skeleton facilitates the electronic conductivity and boosts structural 
      robustness, thus generating wide linear range (0.05-14 and 0.01-10 mM), low 
      detection limit (0.22 muM and 0.07 muM), and a rather low overpotential (-0.15 and 
      -0.05 V) toward H(2)O(2) and N(2)H(4), as well as good selectivity, excellent 
      reproducibility, and admirable long-term stability. It should be highlighted that 
      the operating potentials can compare favorably with those of some reported 
      H(2)O(2) and N(2)H(4) sensors based on noble metals. In addition, good recoveries 
      and acceptable relative standard deviations (RSDs) attained in serum and water 
      samples fully verify the accuracy and anti-interference capability of our 
      proposed sensor systems. These results not only elucidate an effective structural 
      nanoengineering strategy for electroanalytical science but also advance the 
      rational utilization of H(2)O(2) and N(2)H(4) in practicability.
