چکیده مقاله:
Molecular dynamics simulation was employed to examine the structural properties of three nanodroplets (a pure water nanodroplet and two bio-droplets containing poly(A)6 single stranded DNA (ssDNA) and poly(T)6 ssDNA molecules) on graphene sheet. The contact angle and orientation of bases of ssDNA molecule to the graphene during the time were calculated. Results showed that the bases of ssDNA placed parallel with graphene sheet due to π-π stacking interaction between graphene and base. This orientation caused that the contact angle of poly(A)6 and poly(T)6 bio-droplets became greater than the pure water nanodroplet.
