Analysis of π-stacking interactions between the Phe aromatic ring and the SWCNT carbon ring in random-Aβ(16-22)+SWCNT and sheet-Aβ(16-22)+SWCNT systems at 310 K. (A) The PDF of the centroid distance (d) between the Phe ring (each Phe residue is considered) and its closest SWCNT carbon ring. (B–D) The PDF of the angle between the two rings with a centroid distance of (B) 0.3 ≤ d ≤ 0.45 nm, (C) 0.45 < d ≤ 0.65 nm, and (D) d ≥ 0.65 nm. The selection of the three distances is based on the PDF peak in panel A.
