A novel design for magnetic tweezers with wide-range temperature control.
Article in Biophysical journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Single-molecule manipulation technologies have proven to be powerful tools for studying the molecular mechanisms and physical principles underlying many essential biological processes. However, achieving wide-range temperature control has been challenging due to thermal drift that undermines the stability of the instrument. This limitation has made it difficult to study biomolecules from thermophiles at their physiologically relevant temperatures and has also hindered the convenient measurement of temperature-sensitive biomolecular interactions and the fundamental thermodynamic properties of biomolecules. In this work, we present a novel design of magnetic tweezers that uses a reflective coverslip and dry objective lens to insulate the heat conductance between the sample and the objective lens, enabling stable temperature changes from ambient up to 70°C during experiments without significant thermal drift of the instrument. The performance of the technology is demonstrated through the quantification of the free energy change of a DNA hairpin over a temperature range of 22°C-72°C, from which the entropy and enthalpy changes are determined.
