Sapphire is an electrical insulator and it's translucent.
Computer chips containing it can communicate with

Scientists have been using light to move tiny sacks
of fluids smaller than human cells for years. Bigger
versions of these artificial cells that are more
like their biological cousins have been more resistant
to laser manipulation. A new approach shows that
what's inside makes a big difference.
