Nano structures, namely, nano rings and nanoparticles, comprising two\ndimensional, crystalline gold atomic discs were produced on a sapphire\nsubstrate. Nano rings revealed several remarkable properties, namely, an\napparent spatial orientation memory register, an apparent programmed homing\ninstinct and action based on that instinct, usually observed only in living,\nbiological systems. Momentary application of 100 nN force on a nanostructure,\nmother led every mother within the entire scanner area to increase its volume\nand create several daughter replicas. Over time, without the influence of any\napplied external force or stimulus, each daughter, of its own volition,\ntransported itself back to its mother and recreated its original form. The\nresults strongly implied temporal and spatial synchronization between the\ndaughters and their respective mothers. The targeted movement of the daughters\ntowards their mothers implied the existence of a special, yet unidentified new\nforce. Momentary application of a weak force on a gold nanoparticle resulted in\nthe spontaneous transformation of each nanoparticle into a complex and robot\nlike Dalek 3dimensional form. Without the application of any additional\nexternal force or stimulus, we observed a remarkable display of oscillatory\ntransformation between the robot-like forms and their mother nanoparticles\nlasting over 26 hours. The robot-like structures seem to replicate identical\ncopies of themselves.\n
