microscope is used for defect detection. Stages 7 comprise analysis, by naked eye or microscope, while stage 8 aims at post
cleaning and sterilization.
Some analogy to existing NDT techniques, as dye penetrant and magnetic particle, can be identi ed. However, the use of bacteria instead of a dye penetrant presents a greater potential resulting from the wide range of bacterial properties as size, motility, adhesion, reproducibility and survival properties. These “live” attributes can strongly improve the sensitivity of the techniqueto detect surface defects, when compared to the dye penetrant, which is only based on the capillarity and the viscosity of the uid.
In this sense, the new proposed NDT technique can be considered as an “active” technique, opposite to the dye penetrants, which is a “passive” technique. NDT techniques based on ultrasounds and eddy currents to detect harmful bacterial lms is common nowadays, as in attributes can strongly improve the sensitivity of the technique
to detect surface defects, when compared to the dye penetrant,
which is only based on the capillarity and the viscosity of the uid.
In this sense, the new proposed NDT technique can be considered
as an “active” technique, opposite to the dye penetrants, which is a pipelines or aircraft fuel tanks. In such applications, the bio lms are unwanted and must be prevented [11,12]. In this paper the opposite is proposed, that is, to take advantage of bacteria proper-ties and adhesion, in a controlled way, in order to detect defects.
