The combination of biology and nanotechnology is exciting. There is no doubt about it. Doctors are describing a day where they move from treating symptoms to generating new cures and regerating issues. Every tissue in your body, from head to your toe can be regenerated someday. The science will allow us to grow body parts that the human body needs in an outside environment and when needed transferred to the human body. A spinal cord can be created with stem cells and grown in animal test or control conditions and used when a patient needs a replacement. The technology has advanced so much that governments are now investing money. The United States Department of Defense has allocated $20 million dollars to study whole lim generation. Imagine what that can do to help a solider who has lost a limb in the line of battle. Imagine the benefits and the reprucussion that will have on our everyday life.
