“On March 20, 2014, the US Patent & Trademark Office published a patent application from Apple that reveals Apple’s work with spherically shaped nano particles and pigment nano-particles in particular that could be used in inks or dyes and applied to devices via screen printing and spraying processes,” Jakc Purcher reports for Patently Apple.

“If you’re an industrial designer or student in this field, you may find this invention to be of great interest to you. For the rest of us, it’s a little over our heads,” Purcher reports. “Though admittedly, it’s an interesting invention only because it’s a coloring process that could be used with future products made of sapphire.”

Purcher reports, “Apple also notes that ‘another advantage associated with the use of silver nano-particles is their utility in providing an anti-microbial coating to a device.'”
