Nanotechnology/Metallic Nanostructures

=Gold= The red color in some stained glasses has through centuries been made from gold nanoparticles, and its also gold particles that make the red color in many pregnancy tests. Gold nanoparticles are used on many technoogies: they have a red color because of a plasmon resonance and the noble metal makes them good for specific binding of molecules with thiol groups.

Copper
When copper is viewed on the nano level, several changes occur. the temperature of the metal decreases, as well as the fatigue limit decreases. Also, the tensile stress and elongation rate of the copper decreases.
