Touchscreen devices have transformed how we interact with technology, but people with long fingernails often struggle with capacitive screens that don't register non-conductive nails. A student researcher at Centenary College of Louisiana has developed a potential solution: conductive nail polish that could make fingernails touchscreen-compatible.

Manasi Desai, an undergraduate with an interest in cosmetic chemistry, began exploring this problem after realizing existing conductive polishes have significant drawbacks. Current options use additives like carbon nanotubes, conductive polymers, or metallic particles that can be dangerous if inhaled and offer limited color choices, typically resulting in black or metallic finishes.

Working with organometallic chemist Joshua Lawrence, Desai created a clear, colorless formula that can be applied over any manicure without using toxic materials. The research was presented at an American Chemical Society meeting in Atlanta, Georgia. This innovation could eliminate the need for workarounds like using finger pads or carrying a stylus, making touchscreen technology more accessible for people who prefer long nails.
