With the numerous medical nanotechnology applications that different nanoparticles are displaying, are nano particles going to be the cure for most types of cancer? Bio-detectors and drug transport NPs seem to be the wave of the future. They can also rely on their size and unique quantum effects as well as magnetic properties and surface treatments. As with most things in life, nanoparticles are a dangerous double edge that balances their future uses in nanomedicine offset by the dangers of human and environmental toxicity. What other specific ways are NPs equipping doctors with new tools?
