Molecular systems are good candidates for designing the novel generation of nanoelectronic and nanospintronic devices due to their flexible structures. We have theoretically investigated stain-induced spin transport through a DNA chain to control a piezospintronic component. In the current modeling, we have applied a small strain to a tilted DNA chain connected between two leads and immersed it in a heat bath. The results show that a compressing strain can enhance the spin-dependent current up to 300 nA. Via modulating the control parameters, one can control the spin transport characteristic of a DNA-based material for designing an information storage and transport device.
