Electrode potential modified by gelatin surface charge

Key Points

• To investigate the impact of gelatin surface charge on the potential of electrodes.
• Analyzed the surface charge of gelatin-coated electrodes.
• Measured the electrode potential in response to varying surface charges.
• Conducted electrochemical measurements to quantify changes.
• Positive surface charge of gelatin reduced electrode potential by several hundred millivolts.
• Changes indicate a significant effect on biointerfacial interactions.
