A sensor is disclosed. The sensor comprises a substrate; and a gold pattern attached to the substrate, wherein the gold pattern is made from a plurality of repeating units, each unit is made from at least one line having a width of between 100 to 500 nm and a length of between 1 to 50 microns, and wherein a first distance between two neighboring units is between 50 to 1000 nm, and wherein all lines in the pattern, are originated from a monocrystalline gold, therefore, have the same crystallographic orientation with respect to the substrate. |
