TL;DR: It is shown that gold bipyramids exhibit a strongly reduced heterogeneity in aspect ratio and plasmon wavelength compared to commonly used gold nanorods, which translates into a significantly improved homogeneity of the response to molecular binding without compromising single-molecule sensitivity.

TL;DR: A single-particle study wherein single nanospheres bind to a gold nanorod is performed, and the observed plasmon shift is related to the binding location using correlative microscopy and atomic force microscopy.

TL;DR: The quantitative single-molecule counting provides a direct route to quantification and optimization of coupling protocols towards molecularly controlled colloidal interfaces.

TL;DR: The surface plasmon modes of metal nanoparticles provide a way to efficiently enhance the excitation and emission from a fluorescent dye as discussed by the authors, and the top enhancement factors were above 1000fold in 71% of the dimers within a total of 32 dimers measured, and in some cases, they reached almost 4000fold, in good agreement with model simulations.

TL;DR: This work investigates the rotational diffusion in glycerol of much larger objects, single gold nanorods, and shows that heterogeneity appears at temperatures lower than 225 K, even on the length scale of 30 nm, the averaged size of the nanorod.
