Charge transport (CT) is the flow of charge through a medium, in this work we focus on electron CT. Due to the longer timescale of CT in longer chains, nuclear degrees of freedom must be included. In this work, we use the Landauer-B ̈uttiker probe (LBP) method to incorporate dephasing and energy exchange to the system electrons. We first present short systems of length < 1 nm to demonstrate the transition from tunneling to hopping transport mechanism. Next, we demonstrate non-trivial behaviours in high intersite tunneling energy systems. Following, we simulate longer systems up to 50 nm, showing the advantages of different transport mechanisms. We further simulate an alternating-rigidity system based on Geobacter Sulfurreducen by alternating the dephasing conditions. Finally, we apply the LBP method to study chiral-induced spin selectivity in proteins. While the results are preliminary, simulations show asymmetry of the transmission probability for different electron spin species.
