Solving Minimum Spanning Tree Problems Based on DNA Chemical Reaction Networks.
Article in Combinatorial chemistry & high throughput screening, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionDNA strand displacement reactions are emerging as a promising biocomputing tool. The minimum spanning tree problem is fundamental in graph theory. This paper explores the use of DNA strand displacement reaction networks for addressing the minimum spanning tree problem. We also present a computing model that is based on DNA strand displacement reactions.
methodsThe model effectively solves the minimum spanning tree problem by intelligently integrating the three reaction modules of weighted, threshold, and sum. Thus, initially, we encoded the edges in the graph using distinct DNA sequences and effectively assigned the edges their respective weights. Afterwards, the threshold module applied a filter to the weighted edges based on the fluorescence intensity. Ultimately, the sum module gathered the filtered edges to calculate the overall weight of the minimum spanning tree. In order to verify the effectiveness of the proposed method, we conducted simulation experiments using visual DSD software.
resultsThe results of the simulations showed the viability and precision of this DNA computing model in resolving intricate problems.
conclusionFurthermore, this study not only confirms the capability of DNA computing in solving problems related to graph theory, but also offers significant theoretical backing and experimental foundation for the future advancement of DNA-based computer systems and biocomputing applications.
