The relative binding energies ($\mathrm{\Delta }\mathrm{\Delta }{E}_{\mathit{\text{bin}}}^{\mathit{\text{sol}}}=\mathrm{\Delta }{E}_{\mathit{\text{bin}}}^{\text{sol}}(\text{crossing}-\text{stacking})-\mathrm{\Delta }{E}_{\mathit{\text{bin}}}^{\mathit{\text{sol}}}(\text{self}-\text{stacking})$) in aqueous solution of self- and cross-stacking of four different nucleobases (G, A, C and T). The solid line with triangle and dashed line with square stand for the cross-stacking with (5,5) and (10,0) SWCNTs, respectively.
