Cells and DNA
The average human body = ~10-100 trillion cells
Nearly every cell contains DNA; 4 nm wide and uncoiled ~2-3 m long
All DNA in all cells = ~70 trips to sun and back

If Legos Were the Size of Atoms
‣The advantages of working at the nanoscale
Greater control and flexibility building from the ground up
Special properties at the nanoscale

If Legos Were the Size of Atoms
‣Increase flexibility and control but...
How many would you need?
How would you see them?
How would you work with them?
