Could you enrol on these and check the content that would be useful - academy.zimmerpeacock.com/course/introduction-to-biosensors and this this one academy.zimmerpeacock.com/course/electrochemical-techniques-for-biosensor-developers, we provide the content for free so would love some community quality checking
