I don't understand what you are trying to say.
If you construct materials on an molecular level using all the endless possibilities given by the amazing complex biochemistry you can make materials that are 3000 times as strong as steel while being 10 times lighter. Like our hair, which is amazingly strong, and spider silk. Materials like that. We can make a material that is stronger as steel and as light as aluminium that can be streched out two times its lenght, or more.
Nature has only scratched on the surface on what is possible. But building on the atomic level is very complex.
Our bodies have 'factories' made up out of long strings of amino acids. And they are very very small compared to our actual factories. In theory you can create those as well. Instead of using surgury one could construct proteins and enzymes that cure the patient. Just put them in the patients blood and send her or him home and wait.
