Construction a novel photoelectrochemical aptasensor based on multivariate copper-based metal-organic framework for the efficient detection of tetracycline.

Key Points

• The study aims to develop a novel photoelectrochemical aptasensor for the sensitive detection of tetracycline (TET).
• Constructed an aptasensor based on a copper-based metal-organic framework (MOF).
• Evaluated the selectivity, reproducibility, and stability of the aptasensor compared to conventional methods.
• Achieved high selectivity and good reproducibility in TET detection.
• Demonstrated long-term stability, making it practical for diverse applications.
