1 · What the graph read from it

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.

2 · The registry

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

Improving the affinity of nucleic acids to their complements is an important goal for many fields spanning from genomics to antisense therapy and diagnostics. One potential approach to achieving this goal is to use multivalent binding, which often boosts the affinity between ligands and receptors, as exemplified by virus-cell binding and antibody-antigen interactions. Herein, we investigate the binding of heteromultivalent DNA-nanoparticle conjugates, where multiple unique oligonucleotides displayed on a nanoparticle form a multivalent complex with a long DNA target containing the complementary sequences. By developing a strategy to spatially pattern oligonucleotides on a nanoparticle, we demonstrate that the molecular organization of heteromultivalent nanostructures is critical for effective binding; patterned particles have a ∼23 order-of-magnitude improvement in affinity compared to chemically identical particles patterned incorrectly. We envision that nanostructures presenting spatially patterned heteromultivalent DNA will offer important biomedical applications given the utility of DNA-functionalized nanostructures in diagnostics and therapeutics.
