Concentration of leaked methylene blue. Mean concentrations of leaked methylene blue [μg/ml] of the three groups recorded at each day. Since the three spectrometric measurements of each group/point of time showed only minimal deviations, no standard deviations are indicated. Intragoup values of different points of time are connected by a line for better illustration
