Graphene is a popular and interested nanomaterial in terms of electrical properties, so it has been applied to fabricate electrodes for modern electronic devices and sensors. In this work, Dr. Pumidech Puthongkham and Dr. Supacha Wirojsaengthong’s group explored the properties of laser-induced graphene electrode, an emerging electrode in the present decade for using in electrochemical applications, but it lacks the fundamental investigation. This research revealed the effect of electrode size on structural and chemical properties of the electrode, which directly affected the electrochemical properties of the laser-induced graphene electrode. This result is foundational for developing the modern electrochemical sensors for food, environmental, and clinical applications.
