Fingerprintless screen soon to be seen in future smartphones

A group of researchers have found a way to create smudge free glass that could be used in the touchscreen phones of tomorrow, to prevent  fingerprints.  Researchers from the Max Planck Institute for Polymer Research in Mainz applied candle soot to glass and then coated it in silica to keep it in place. The glass is then heated to 600 ºC for calcination, which makes the soot transparent

To test,  different oils and solvents were applied, but the glass’ superamphiphobic properties stayed on. The future could be fingerprint-free for all our shiny new devices.
