Monitoring Simultaneous Distance and Orientation Changes in Discrete Dimers of DNA Linked Gold Nanoparticles.
Article in The journal of physical chemistry. C, Nanomaterials and interfaces, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Important optical properties of discrete pairs of DNA tethered gold nanoparticles, including their scattering cross-section and resonance wavelength, depend both on the dimer structure and the refractive index of their immediate environment. We show that far-field polarization microscopy aids the optical identification and interpretation of structural changes including hinge motions and nanoscale distance changes in individual assemblies. Grecco and Martinez have shown in their theoretical work that the interparticle separation dependent polarization anisotropy of discrete nanoparticle dimers enables nanoscale distance measurements (Optics Express 2006, 14, 8716 - 8721). Here we implement this approach experimentally and evaluate measured polarization anisotropies in the framework of a dipolar coupling model. We use polarization sensitive darkfield microscopy to resolve simultaneous distance and orientation changes during the compaction of discrete pairs of DNA tethered gold nanoparticles by fourth generation polyamidoamino (PAMAM) dendrimers. The relative contributions from interparticle separation and refractive index variations to changes in the light polarization and scattering intensity are quantified and compared.
