Offence not intended, but those patches are homeopathic, not nanotech. I also happen to believe homeopathic medicine is bad science. With the extremely dilute concentrations of active ingredients which almost all homeopathic products contain, I'm of the opinion that any positive effect is psychosomatic. (I've seen people participating in drug trials exhibit improvements in physical condition from nothing more than a chalk-based placebo.) Those LifeWave products have potencies of 10x, 30x & 1LM. 1LM is orders of magnitude more dilute than 10x (which in and of itself is ridiculously weak; 1x potency is one tenth of the original concentration, 2x is one one-hundredth, and it increases in powers of ten - so 10x is a concentration of 1 in 10,000,000,000 parts. at 24x you're nearing Avogadro's limit, at which point you have about ~10% chance of finding a single molecule of the original ingredient."
Surprise surprise, she had nothing of substance (ha) to riposte with.
With your bare hands?!?
