Recent advances and challenges in temperature monitoring and control in microfluidic devices

open access: yesELECTROPHORESIS, Volume 44, Issue 1-2, Page 268-297, January 2023., 2023
Abstract Temperature is a critical—yet sometimes overlooked—parameter in microfluidics. Microfluidic devices can experience heating inside their channels during operation due to underlying physicochemical phenomena occurring therein. Such heating, whether required or not, must be monitored to ensure adequate device operation.
