Outline of Final Research Achievements

We propose a method for evaluating the detergency effects of micro/nanobubbles that uses adenosine triphosphate (ATP) as an index. We also examined a procedure for generating soiled materials (i.e., soiled fabrics) by selecting the model contaminant needed to verify the detergency effects of micro/nanobubbles.　For evaluations of the detergency of gelatin soiled materials such as slide glasses, we found that micro/nanobubble water increased the RLU that reflects the quantity of ATP in the residual liquid, indicating the detergency effects of micro/nanobubble water. Significantly lower RLU values for the residual solution and blood soiled fabric after washing with ozone nanobubble water than with ion-exchanged water. Since lower RLU values indicate smaller amounts of ATP and superior cleanliness, the results demonstrate the effectiveness of ozone oxidation in ATP removal (cleanliness).
