Morgenstern, Markus  asked the Naked Scientists:
Hello Chris,

My daughter Pauline (she is 5) asked me today about how are bacteria able to stick to human skin?

By the way newbielink: [nonactive] very much!



What do you think?

As objects decrease in size, the force necessary to adhere to something becomes very low. A drop of water for example will adhere to a surface through electrostatic adhesion alone. Bacteria really don't need to do much other than attract the moisture on our skin in the first place.
