Abstract

The adoption of single-use plastics for fabricating lab-on-chip devices used in sensors, chemical and biomedical processes is escalating into a major environmental issue. To address the global need for developing long-term sustainable solutions, we present wood microfluidics as an alternative for electrochemical sensing. The lab-on-wood-chip (LOWC) device developed in this study demonstrated (i) versatility in electrochemical applications (electropolymerization and corrosion analysis), (ii) stability under highly acidic (pH 0.5), basic (pH 14.0) and varied temperature (4°–60 °C) conditions (iii) long-term consistency in performance (>12 months), and (iv) potential for on-field nitrate sensing towards environmental monitoring – in a cost-effective, simple and sustainable manner.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
