To study the effects of microwaves on structural and functional properties of tuna myoglobin at 1.95 GHz, a frequency used by new wireless microwave communication systems.
In order to state safety guidelines it seems appropriate to start by excluding non-specific effects on dynamic and structural properties of fundamental biomolecules such as proteins (proteins are susceptible, in principle, to the action of electromagnetic fields).

|ばく露装置の詳細||The sample (3 ml of solution) in a polystyrene cuvette (10 x 10 x 35 mm) was placed vertically in the waveguide where the incident E field (vertical) was maximum.|
|Additional information||The sample temperature at the beginning was 25 ± 0.1 °C, it increased to 30 ± 0.1 °C in about 30 min, and it remained at that value for the rest of the exposure period.|
The data indicate that, at least for the native state of the protein, microwave perturbation does not affect the structural organization of the myoglobin or its internal dynamics and CO binding affinity.
