This work reports a simple and inexpensive way of producing a device that displays a sensitive response for a given biomolecule. The device consists in hydrophobic paper, covered by a graphite home-made ink and by a sensory material, a plastic antibody tailored on-site by an electrical stimulus.
The target biomolecule was carnitine, a potential biomarker in ovarian cancer. The concept presented herein may be extended to other biomolecules, including other cancer biomarkers
