Sweat pore mapping using a fluorescein–polymer composite film for fingerprint analysis†
Abstract
A simple but efficient sweat pore mapping method based on a fluorescein–PVP composite film was developed for fingerprint analysis. The composite film displays a fluorometric turn-on response upon contact with a small quantity of water secreted from human sweat pores, allowing precise mapping of sweat pores on a fingertip.
