STM Image (IMAGE) Max-Planck-Gesellschaft Caption Fig. 1: An STM image of individual L and D Di-phenylalanine molecules adsorbed onto Cu (110). A human body has more than one thousand trillion trillion molecules with about one hundred thousand different shapes and functions. The researchers have followed the interaction between two molecules to show the basic mechanism underlying chiral recognition.
