Cosmetic concern - Down to Earth, India
Thanks to nanotechnology, that allows grinding particles to atomic levels, you now have face creams that spread so smoothly on your skin that only a transparent sheen is visible, no layers.

While that seamless make-up is desirable, cosmetics using nanoparticles might not be as harmless as they are believed to be. Recent studies link them to cancer and cell death. Although nanotechnology is used in about 600 consumer products, including face creams and toothpastes, there have not been enough risk-assessment studies and regulation of their use in personal care products.

Scientists: Humans and machines will merge in future - CNN, USA
Transhumanists anticipate a coming era where biotechnology, molecular nanotechnologies, artificial intelligence and other new types of cognitive tools will be used to amplify our intellectual capacity, improve our physical capabilities and even enhance our emotional well-being.

By 2020, Kurzweil predicts a second revolution in the area of nanotechnology. According to his calculations, it is already showing signs of exponential growth as scientists begin test first generation nanobots that can cure Type 1 diabetes in rats or heal spinal cord injuries in mice.
