New Polymer Ideal For Secure Data Storage

Clever geometry is the basis of a new material that is said to be ideal for secure data encryption and dense optical information storage. The material consists of a lattice of onionlike spheres in which the particle core and its layers each contain a different dye. The material can hold four or more pieces of information in one spotónot just two as in binary optical data storage. And it opens a door to high-density three-dimensional optical data storage
