WebFeb 25, 2024 · The parameters needed for interatomic energy calculation were taken from the force fields RNA.YIL (39, 40) for RNA and from the general amber force field (gaff2) for the dyes. The MD simulations in the production phase were carried out using constant temperature ( T = 300 K) and constant pressure ( p = 1 atm) over 80 ns. WebBecause the fCNTs do not belong to any standard class of organic molecules, we utilized the general amber force field, gaff2 , with parameters set for the force field parameters values [16,17], as reported in Section 2.1. The described approach leads to the force field, which treats the fCNT as a large molecule with only pairwise-additive ...
