I don't know much about nano-technology, and so I viewed the patch with hope but not with confidence at first. Once I put it to my pounding head ache, and it went away in seconds, I was completely caught off-guard! Then I tried it another time, and then I had a friend try it--each time it helped the head ache's go away. Very impressive--I love that it is based on my boys's own electrical energy--that it is the body healing itself.
