Preparation and Property Study of Cu2O/Co3O4 Nanowire Arrays
Hydrogen sulfide(H2S)has been identified as the third endogenous gasotransmitter,and its abnormal concentration is closely related to many diseases.If a fast and highly sensitive sensor could be obtained to monitor the dynamic changes of H2S in organisms,the controllability of these diseases would be greatly improved.In this study,a Cu2O/Co3O4 nanowire array-based biosensor material was proposed,which showed good sensitivity,selectivity,and stability to H2S in human blood based on interface conductivity modulation and sulfidation reaction.This work demonstrates the reliability of Cu2O/Co3O4 nanowire arrays for rapid detection of biological hydrogen sulfide using portable sensors.
