Patent ID: 6855749

Claim:
A nanocomposite for administration in a human or animal comprising: an acrylate matrix; nanofillers comprising one or more elements selected from the group: barium, bismuth, cerium, dysprosium, europium, gadolinium, hafnium, indium, lanthanum, neodymium, niobium, praseodymium, strontium, tantalum, tin, tungsten, ytterbium, yttrium, zinc, and zirconium; wherein the nanofillers have a domain size less than 100 nanometers; wherein the nanofillers are mixed into the acrylate matrix at a loading of less than 80 volume percent to form a nanocomposite; and wherein the composite exhibits a transparency to light that differs by more than 20% as compared with the transparency to light exhibited by a composite of similar composition with fillers having a domain size of at least one micron.
