Wood inspection and durability testing of wood against microorganisms, as fungi, play an
important role in forestry and wood-related material industries. An efficient testing
method is required in order to facilitate inspections and to provide the accurate and
precise assessment process. Monitoring volatile organic compounds (VOCs) released from
wood substrates and from fungal metabolisms are marker compounds of the wood
condition, i.e., indicating the type and stage of fungal infection. Insect antennae, which are
recognised for their high sensitivity and selectivity in odour perception, are an alternative
method for wood testing. On the basis of intact insect antenna biosensor it is possible to
monitor wood released VOCs with high selectivity. This technique can be a complement
to the traditional wood testing methods, providing a high throughput and non-destructive
method.
