Development of a Fluorescein-Polymer Composite Film for Human Sweat Pore Mapping |
| 초록 |
Fingerprint analysis serves as one of the most reliable methods for personal authentification. The vast majority of fingerprint analyses are based on ridge structures on fingertips. Herein, we present the results of studies leading to development of a widely applicable sweat pore mapping system that also can be used for personal authentification. The new system utilizes a small molecule-polymer composite film and fluorescein as a water-sensitive probe molecule that fluoresces in the presense of tiny amounts of sweat. The hydrophilic polymer matrix, polyvinylpyrrolidone (PVP), is employed to effectively capture the aqueous components in sweat. The fluorescein-PVP composite film enables excellent fluorescence mapping of sweat pores on a fingertip. Matching of the sweat pore map obtained in this manner with latent fingermarks enables an accurate identification of individuals. |
