Overview
- Researchers at Centenary College of Louisiana, who presented their results Monday at the American Chemical Society meeting, unveiled a clear polish that makes nails register on capacitive touchscreens.
- The team suspects the coating works through proton exchange in an acid–base pair that nudges the screen’s electric field enough to count as a tap.
- Tests of 13 clear polishes with more than 50 additives found the strongest responses from a taurine and ethanolamine blend.
- The prototypes stop working after hours or a day, need thick blobs instead of a thin coat on nails, and raise concerns such as ethanolamine skin irritation and gritty, speckled finishes.
- By pursuing a clear, particle‑free chemistry, the project seeks to aid users with long nails or callused, dry, or gloved fingertips without the dark finishes and inhalation risks linked to carbon or metal additives, and a provisional patent is in place while reformulation continues.
