    Abstract
    In this study, two important biomarkers, namely glucose and uric acid, were detected in different biological fluids using a highly sensitive and selective chitosan-/nano-based electrochemical microfluidic paper-based analytical device. A graphite/chitosan/polyethylene glycol mixture was used as bare working electrode and counter electrode with silver ink being used as quasi-reference electrode. Graphene, multiwall carbon nanotubes, and Fe 3 O 4 nanoparticles were used to improve sensitivity as well as selectivity of the working electrodes. The developed chitosan-/nano-based...
