Bharat Bhushan, a professor at Ohio State University and Wei Tang, an engineer at China University of Mining and Technology used atomic force microscopes to observe the responses of pseudo and rat skins to a generic skin cream. The result? Even at a scale of 100 nanometers — or one-thousandth the width of a human hair — all the samples reacted in a similar fashion."
