NSF GenNano Competition 2015 - 16 Winner Nanoman

The video introduces Nano Man, a superhero representing nanomedicine, designed to combat cancer depicted as a crab monster. It highlights the role of nanotechnology in creating highly sensitive sensors for early cancer detection, surpassing traditional methods. The University of Pennsylvania is developing a sensor more sensitive than a dog's nose, capable of detecting skin cancer early.

What is the significance of detecting cancer earlier as mentioned in the text?

Describe the capabilities of the sensor being developed at the University of Pennsylvania.
