Development of an Innovative Flexible Paper-Based Methanol Fuel Cell (PB-DMFC) Sensing Platform – Application to Sarcosine Detection

•Novel hand-made methanol fuel cell designed on a paper substrate.•Cathode and anode designed in both sides of the paper substrate.•Anode modified with a molecularly imprinted polymer for sarcosine.•Fuel cell operation dependent upon sarcosine concentration.•Sarcosine as a cancer biomarker that needs to be monitored.
