Description
The Moiré-fringe image of a 30 nm decahedral gold nanoparticle shows five-fold rotational symmetry (black fringes) that results from serial twinning and shows the internal distortion of the atomic structure (indicated by the gradual change of the color fringes) that accommodates this unique geometry. The Moiré-fringe image was extracted from the original TEM image taken on the spherical-aberration-corrected Tecnai F20 at the CEMES-CNRS in Toulouse, France. Such particles have tremendous potential as components of nanoscale plasmonic devices for imaging, cancer therapy, and biosensing among other applications.
