TEDMED talk by Anita Goel: How will nanotechnology be used in the body?
Theme: the interaction between biomedical science, physics and nanotechnology
It comes from an understanding of nanotechnology, physics and, the cellular environment; and being able to manipulate these factors. They found that the degree of stretch of a DNA strand affects the direction of polymerase of a double stranded DNA.
apparently our current pathogen identification and detection systems are not useful in diagnosing unknown pathogens. How were they able to extract the DNA/RNA without the need for culturing and skipping the bioinformatics stage?
My idea
1. Instead of waiting and checking a patient until they are sick. why not design a nanobot that is attached to the internal environment in the body. Thus, whenever there are slight changes in the body temperature or if a pathogen is detected. It can be easily translated to the patient before they can feel the symptoms.
2. Use DNA to store information instead of USB or hard-drive. It takes up less physical space and has a much more efficient tools [enzymes] that protects it from being damaged.
