Fig. 2: Morphology analysis of Adenine oligomer-induced chiral gold nanoparticles.

a Low-magnification SEM image of chiral gold nanoparticles synthesized with A50 oligomers. b (Left) High-magnification SEM image of chiral gold nanoparticle synthesized with A50 oligomer viewed from <100> and <111> direction. (Right) 3D modeling of chiral gold nanoparticles synthesized from A50 oligomers from <100> and <111> perspective with chiral motif shaded in red. A point denotes the corner point of the nanoparticle and B point denotes the center point of the nanoparticle. The generation of the chiral motif is marked with a red dotted line and the rotational direction is marked with a white arrow. c Time-variant morphology SEM images of chiral gold nanoparticles synthesized with A50 oligomers.
