Multifunctional Dopamine‐Based Hydrogel Microneedle Electrode for Continuous Ketone Sensing (Adv. Mater. 32/2024)

This is the authors' abstract. We don't add key points for this paper.

Hydrogel Microneedles The hydrogel microneedle continuous ketone monitoring (HMN-CKM) sensor is a skin-compatible patch designed to alert patients with diabetes at the onset of diabetic ketoacidosis. It leverages the catechol-quinone chemistry of dopamine to monitor ketone bodies in interstitial fluid, while dopamine also serves as the crosslinking agent for the HMN patch.
