Title: "Enantiomer separation using magnetic substrates"

Abstract:Living organisms rely on chiral molecules, such as nucleic acids and proteins. Organisms contain only one enantiomeric form of a molecule, a selectivity that has prevailed through evolution. We claim that the chiral induced spin selectivity (CISS) effect may explain why enantiomeric purity might provide an advantage in biology. CISS is an electronic phenomenon in which electron transmission through chiral molecules depends on the direction of the electron spin. Thus charge displacement and transmission in chiral molecules generates a spin-polarized electron distribution. This effect; enhance electron transfer in proteins, enable nano metric charge separation, and explain bio-recognition. From the application point, by utilizing the CISS effect we realized simple spintronics devices, and enable generic and simple enantiomer separation using magnetic substrates
