In their research article -- A social chemosignaling function for human handshaking-- Frumin et al. at the Weissman Institute of Science find that people use the touch of a handshake to sample and sniff signalling molecules.

During the experiment, around 280 people were greeted either with or without a handshake. They were filmed using hidden cameras and observed to see how many times they touched their face. One finding of the study was that people constantly sniff their own hands -- keeping a hand at their nose about 22% of the time. Subjects greeted with a handshake significantly increased touching of their faces with their right hand. However, this only seemed to be the case when the subject had been greeted by a person of the same gender.
