Yes. Researchers have made wood-based microfluidic devices that detect proteins, mix fluids, identify microbial contamination, and sense nitrate. These remain research-stage demonstrations—not evidence that wood has replaced plastic or that wood chips are ready for routine clinical or commercial use.
What can wood microfluidics do?
Microfluidic devices guide small volumes of liquid through tiny channels for tasks such as mixing samples or detecting target substances. Wood is porous and absorbs liquid, so researchers have had to shape channels and control how fluid moves through the material.
Protein detection, mixing, and microbial screening
In a 2019 proof-of-concept study, Andar and colleagues used laser engraving and mechanical fabrication to make wood devices for surface-plasmon-coupled fluorescence detection of proteins, T- and Y-shaped channel mixing, and rapid detection of microbial contamination. The team applied surface coatings to limit wicking. In the experiments reported, the devices performed as well as or better than plastic counterparts; that result applies to those tests, not to every assay or use. The paper reports measurements of recombinant GFP standards across 1.5–25 ng/μL and 6XHis-G-CSF across 0.1–100 ng/μL in cell-free translation systems. Those are experimental measurement ranges, not clinical or market statistics. Read the 2019 paper in Analytical Chemistry.
Electrochemical studies and nitrate sensing
A study published in October 2025 extended the work to electrochemical applications with a lab-on-wood-chip device. Its abstract describes electropolymerization, corrosion analysis, and proof-of-concept nitrate sensing for environmental monitoring. The authors report testing at pH 0.5–14.0 and temperatures of 4–60 °C, as well as performance consistency for more than 12 months. These are findings reported by that study, not independently replicated field performance. Read the 2025 study in Chemical Physics Letters.

How researchers make the devices
Fabrication methods and materials vary by study; there is no universal wood recipe. The 2019 work used birch plywood in its proof-of-concept devices, with laser engraving or mechanical methods to form channels. Chemistry World reports that the group tested coatings including PMMA and cellulose acetate before selecting Teflon for the reported devices. Researchers were also exploring more environmentally benign options such as vegetable oils and beeswax. The later electrochemical study describes a laser-engraved device made from commercially available balsa wood sheets. Chemistry World’s 2019 report describes how the first trials began with samples of wooden flooring obtained from a local hardware store.
The coatings address a central engineering problem: untreated wood draws liquid into its structure, which can interfere with predictable flow through a channel. But coatings and laser processing introduce their own variables, and results from one combination of wood, coating, and fabrication method cannot automatically be transferred to another.

Where wood may have an advantage—and where it falls short
The motivation is to explore renewable, readily sourced materials for devices that may be used once and discarded, potentially reducing reliance on conventional nonbiodegradable plastics. The 2019 paper presented its devices as proof of concept for point-of-care applications; it did not establish clinical use. Whether wood is preferable depends on the assay and the whole device, not just the channel material.

Why clinical and environmental claims need caution
Material variability matters when an assay is sensitive to substances released by the device itself. Chemistry World reports concerns that birch can release sugars, amino acids, and aromatic compounds into aqueous media, potentially affecting clinical assays. Chris Lowe, a biotechnologist at the University of Cambridge, is quoted warning that “the chemical composition of birch is extremely variable” and that variability “could be exacerbated by charring created by the laser etching and inconsistencies in the Teflon-coating procedure.” These are reasons to test each material-and-process combination for the intended assay, not proof that every wood device will contaminate a sample.

Wood’s lack of transparency also limits analyses that depend on seeing through the device. Chemistry World reports this limitation in the context of wood microfluidics; it is a practical constraint, not a claim that all optical detection is impossible.
Nor does a wood body make a complete device environmentally harmless. Coatings and other components may not be biodegradable, reagents may not be environmentally benign, and residues from composted devices could require hazardous-waste handling, according to concerns raised by Chemistry World. Without lifecycle and waste evidence for a particular design, claims about its disposal or environmental benefit should remain qualified.

What the research does—and does not—establish
- Established in specific demonstrations: wood can be formed into small fluid channels, and proof-of-concept devices have performed protein detection, mixing, microbial screening, electrochemical studies, and nitrate sensing.
- Still unresolved for broader use: whether results can be reproduced reliably across wood stocks, coatings, fabrication runs, and sensitive assays.
- Not established by these studies: routine clinical readiness, broad superiority to plastic, a comprehensive cost advantage, market adoption, or lower lifecycle impact.
A laser engraver and suitable wood stock are relevant fabrication tools, but the studies do not endorse a commercial engraver, establish that consumer machines are suitable, or identify a retail device with validated performance. Buying equipment alone does not reproduce the researchers’ results.
