Dear Dr,

I am reaching out after reading your article titled "A graphene-based electrochemical sensor for sensitive detection of paracetamol" with great interest. I would like to ask you a few questions regarding certain aspects of your study.

Could you please explain the basis on which you selected the potential values when studying the influence of the accumulation potential on the Ip of paracetamol at the graphene/GCE interface?

Thank you in advance for your time and assistance. I look forward to your response.

Best regards,
