To provide a method of metal plating to give a metal plating coating with excellent luster and high corrosion resistance and wear resistance. The invention being particularly well suited when establishing connectivity between wireless networks, such as based on IEEE 802 standards, and traditionally wired network protocols, such as TCPIP and UDP. When we make the number of elements in the array large enough, we insure that to a high degree of probability, the pattern of measured array cell characteristics for an ICID embedded in any one IC will be unique and distinguishable from such patterns measured by ICIDs embedded in millions of other ICs. The RNA may then be used directly in a variety of enzymatic reactions and molecular biology techniques.
