Fabrication and characterization of disposable sensors and biosensors for detection of formaldehyde

► Pt-SPCEs and SPCPtEs have been characterized for the determination of formaldehyde. ► Precision may be improved by modifying SPCPtEs with alcohol oxidase. ► The capability of detection of these biosensors is 60 μmol L−1 for α = β = 0.05. ► Their application to the analysis of commercial samples for histology is viable.
