The composite … SpletN2 - In this study, we present a simple method for mapping sweat pores using a water-soluble polymer matrix film. Local adsorption of sub-nanoliter water secreted from sweat pores on human fingertips creates discrete microdimples on the hydrophilic polymer film. These microdimples can be readily visualized by a conventional optical microscope.
