Zone/region of inhibition (diameter) in mile meter.

Response	Definition
Resistant	If bacteria are unaffected by an antibiotic with or without nanoparticles. In this situation, the inhibition zone diameter will be smaller. This means bacteria are not completely inhibited
Susceptible	If bacteria are positively affected by a specific antibiotic with or without silver nanoparticles. In this case, the inhibition zone diameter will be larger. This means the bacteria are completely inhibited
Intermediate	If bacteria are poorly affected by a specific antibiotic with or without silver nanoparticles. In this case, the inhibition zone diameter will be intermediate, since the growth of microorganisms is stopped to some extent by the medicine
