In this artistās conception of a simple mobile cell-repairer diamondoid nanorobot, the internal storage and distribution subsystems are highlighted in blue. Diamondoid-based medical nanorobots such as the simple mobile cell-repairer shown in this artistās conception may offer substantial improvements in capabilities over natural biological systems, exceeding even the improvements possible via tissue engineering and biotechnology, possibly providing cell surgery abilities and extreme life prolongation. In this image, the nanorobot approaches a cell targeted for repair.
