UiO-66-derived nano-separation microelectrode for in vivo dopamine sensing with high sensitivity and selectivity

Key Points

• The aim is to develop a highly sensitive and selective electrochemical sensor for in vivo dopamine detection using a UiO-66-derived material.
• Developed a UiO-66-(COOH)2-functionalized electrochemical sensor for dopamine detection.
• Assessed sensitivity and selectivity of the sensor in vivo.
• The sensor demonstrated high sensitivity for dopamine detection.
• Selectivity was significantly improved compared to conventional methods.
