Ultra-sensitive photoelectrochemical aptasensor based on a CdIn2S4/ZnSnO3 composite for the detection of adenosine triphosphate

Key Points

• The aim is to develop a highly sensitive sensor for detecting adenosine triphosphate (ATP) using a composite material.
• Utilized a CdIn2S4/ZnSnO3 composite for sensor construction.
• Conducted photoelectrochemical measurements to assess ATP detection capabilities.
• Tested sensitivity and specificity of the aptasensor with biological samples.
• The sensor demonstrated ultra-sensitive detection of ATP with a low detection limit.
• High selectivity against other similar molecules was observed.
• Results indicate strong potential for early disease detection linked to ATP levels.
