“…Despite its inevitability in our daily lives, the repetitive and excessive use of detergents may be detrimental to health. , Excess detergents on skin can cause skin problems, and some detergents penetrating through the skin may induce aplastic anemia. − Furthermore, they may damage the nerve system and promote certain cancers . For these reasons, it is highly in demand to quickly and reliably measure the amount of detergents left after cleaning. − …”

A superhydrophobic surface was realized on a glass substrate and on the inner wall of a capillary tube, employing a combination of ZnO nanorod arrays and stearic acid. The vertical ZnO nanorod arrays were grown by a unique two-step solution method consisting of a seed formation step and nanorod growth step. Stearic acid appeared to be coated over the tips of ZnO nanorod arrays, increasing the possibility of air trapping in the nanorod forest. A water contact angle of 156.3°was demonstrated on the surface-modified glass, and it was attributed mainly to the air-trapping effect. The surface-modified glass substrate was used for contact angle measurements of detergent solutions, and the contact angle was found to monotonically decrease with increasing detergent concentration. Similarly, it was disclosed that the capillary height consistently decreased as a function of detergent concentration. These results indicate that contact angle measurement or capillary rise measurement may be a simple and practical way to detect the residual detergent concentration in water.
