In decorating the film with receptors, this conductance is thereafter modulated by the capturing of specific targets, demonstrated herein with C-reactive protein. This entirely reagentless and single step marker quantification is relevant to the drive of moving assays to a scaleable format requiring minimal user intervention.engBiosensorsC-reactive proteinMolecular scale conductancePoint-of-careReagentlessArtigo10.1016/j.bios.2020.1127052-s2.0-85095432701
