Electrochemistry as a Tool for Redox‐Based Bio‐Information Processing

open access: yesAdvanced Science, Volume 12, Issue 36, September 25, 2025.
Redox is a modality that is native to biology and accessible to electronics through electrochemistry. Imposed electronic inputs are transduced into redox signals that can probe for bio‐information or actuate biological responses. Measured electronic output responses are analyzed to reveal actionable information.
