Page "Nanomedicine" Paragraph 30

Using drugs and surgery, doctors can only encourage tissues to repair themselves.

With molecular machines, there will be more direct repairs.

Cell repair will utilize the same tasks that living systems already prove possible.

Access to cells is possible because biologists can insert needles into cells without killing them.

Thus, molecular machines are capable of entering the cell.

Also, all specific biochemical interactions show that molecular systems can recognize other molecules by touch, build or rebuild every molecule in a cell, and can disassemble damaged molecules.

Finally, cells that replicate prove that molecular systems can assemble every system found in a cell.

Therefore, since nature has demonstrated the basic operations needed to perform molecular-level cell repair, in the future, nanomachine based systems will be built that are able to enter cells, sense differences from healthy ones and make modifications to the structure.
