Spin based properties, applications, and devices are commonly related to magnetic effects and to magnetic materials. In the recent years a novel effect was demonstrated, the chiral induced spin selectivity (CISS) in which it was found that electron transmission through chiral molecules is spin dependent.[1] This effect opens the ability to produce spin polarized electrons without magnetic material. We will present the theory explaining the effect and its relevancy to electron transfer in bio-systems [2,3] and in spintronics applications. [1] R. Naaman, D.H.
